if needed. It is not intended to assign copy rights or any other
credits or privileges.

1. Annoying beeps and chimes.
   1a. Reverse warning beep.
       Was a hot topic on the internet for a while. To my knowledge
       nothing was done about it yet. Best solution I heard was to 
       have a switch that can allow the driver to activate the horn
       if needed, or keep it quite otherwise. (many)
   1b. Door open chime.
       A way to disable the rather loud chime when a door is open!
       Maybe just pressing one of the buttons on the internal keypad
       to mute the chime until the door is open again. (Greg Hanssen, Kodama)

2. State of "re-gen" indicator.
   It would be great to have an indication, on the display, of
   "how much" energy is being put back into the batteries when
   "cost down" is pressed or brakes applied (or both). We all
   are trying to fine tune our driving habits and an indicator
   like that can help tremendously. (many)
   2a. In "power usage" mode have the bars come down from the TOP 
       to indicate regen. The bars all disappear (as at present) 
       when there is equilibrium, but then when there are 100 watts 
       of net regen, just the very top bar lights up, when there 
       are 500 watts, the top two bars light, 1000 watts, the top 
       three bars... and so on. No matter what, the bottom bar 
       should not light up so as not to confuse regen with power 
       usage. This feature require no modifications to the display 
       unit and resolution of the bars is maintained.  (Tom Dowling)

3. More functionality using the door entry code.
   To get the car going, we now need to enter the car entry code, 
   get in, enter the "start" code, wait for the car to "boot up"
   and then we are ready to go.
   Since it is all in the programming anyway, here is a suggestion:
    Add a 6th "function" digit entered after the code to do one of
    several things:
    - Turn on the car
    - Open the trunk
    - Raise the windows
    - Lower the windows
    - "Precondition-now" (Start the AC or Heater now while on shore
      power.)           (Avi Hershkovitz, Chris Yoder)

4. Power setting on the cruise control.
   4a. Cruise control is great. Especially with this responsive 
       car. When using the cruise control, I'm dismayed when the 
       "power used" goes over 50% - to keep up the speed over a 
       hill for example. It would be nice to have a "power saving 
       mode" for the cruise control, that when turned on, will 
       keep the speed as long as power used doesn't go over , 
       say, 55% . (Kodama, Avi Hershkovitz)
   4b. Also, we'd like the coast down button to control whether 
       the cruise control allowed the car to coast & gain speed 
       going down-hill or to engage the re-gen and keep the speed 
       steady. thus on the hills you'd speed up going down and 
       coast up next. This is more efficient use of power and if 
       I'm driving for range I'll use these tricks. (Chris Yoder)
   4c. Buttons for speeds, i.e. 25m/h, 30m/h, 45m/h, 55m/h... 
       I don't really car how fast I drive, so I just drive 
       exactly the legal limit using the auto-pilot. Only annoyance
       is having to set it again after stopping briefly at a red
       light. (Dirk Harms-Merbitz)

5. A 4 seater.
   Being a young family with two kids - a two seater car is not
   the best fit. My next EV will have to be a 4 seater or it will
   be vetoed by my wife! I hope to stay with GM. So please - give
   us a back seat. (Avi Hershkovitz)
   NOTE!: Make the 4 seat a separate model. Don't take away the 
   2 seat sports car model, so many of us love so much. (Chris Yoder)

6. Optional longer charger cord.
   Longer cord will allow better placement of the charger in the
   garage. It's been a year, but we struggled a lot with that issue
   when the car arrived. I still need to back into my garage with 
   my EV1 because the best place for the charger (noise considerations)
   was close to the garage door. (Avi Hershkovitz)

7. Preconditioning.
   7a. "PRECONDITION NOW!" - Start an A/C or Heater precondition 
       starting immediately. Will run for no more than 15 minutes. 
       (Chris Yoder, Kodama)
   7b. Allow preconditioning WITHOUT being attached to a charger.
       This will allow a driver with full batteries to enjoy a
       preconditioned cabin at all times. (Alec Proudfoot)

8. Remote Control.
   This is stolen directly from the Honda EV+. I'd like a remote control
   that would allow me to check the state of charge from inside the house.
   This remote would also have a "precondition-now" button. It would also
   unlock the car and open the trunk but not start it (code would be
   required to start.) (Chris Yoder)

9. Storage.
   9a. A glove compartment. (Chris Yoder, Kodama)
   9b. A shallow lockable storage hatches where the shelf behind
       the seats is currently located (look at the Honda Del Sol
       for an example). (Kodama)
       Another example: A custom storage box design and built by
       Loren Nielsen. (Loren Nielsen) 

10. State of charge and range.
    10a. Digital readout of battery charge (%), both for the pack
         and for the individual modules. Currently this information is
         available only for the entire pack and is only available from
         the 240V wall charger. (Kodama)
    10b. Digital readout for the auxiliary battery state.
    10c. Digital readouts of power use (e.g. amps) vs. 11-bar nonlinear
         display. This would help our awareness of power use by the different
  car systems and allow us to train ourselves in optimal driving
  techniques. (Kodama)
    10d. An explanation of how the state of charge is calculated - In
         addition, perhaps a "min" and "max" range envelope display would
  allow us to get a better estimate of how much further we could go
  based on our knowledge of what is ahead (e.g. freeway vs. surface
  streets). (Kodama)
    10e. Increase the resolution of the state of charge "bars" - 
         Change the bars from "all-or-nothing" to "thermometer" bars
         that progress from the left in 1/10 of a bar increments. 
         that would give a percentage of charge reading to the nearest
         1%, but would still convey the same at-a-glance information
         as at present. (Tom Dowling)
    10f. Show charge state on dash. This could be accomplished by turning
         off the "MI" indication of the range estimator, perhaps after a
         code is typed in, then defaulting back to estimated range when
         the car is unplugged from the charger. This is very important if
         the new Gen 2 charger has no charge percentage indication.
         (Alec Proudfoot)
    10g. Ability to see odometer during charge cycle. (Michael Schwabe)

11. Braking.
    An indicator showing when re-gen and friction braking is being used -
    This would allow us to train ourselves to brake efficiently as well
    as make it unnecessary to use the coast-down feature when it would be
    safer to indicate to drivers behind the car that the car is slowing
    down. (Kodama)

 12. Controls and switches.
     12a. Move more of the controls on the central console elsewhere to 
          make it unnecessary to look down at the console when selecting 
   a control. For example, the window controls could be put in the 
   more traditional place (on the respective doors). (Kodama)
     12b. Replace the shift lever with a button select to improve the driver's
          access to the controls currently blocked by the shift lever. (Kodama)
     12c. Security code - Provision should be made for optionally accepting
          a longer code. Placing the security keypad in a less visible
   location is also very desirable for more privacy while keying
   in the access code. (Kodama)
     12d. Valet Code - additional code allowing only reduced-performance 
          (and possibly limited-range) operation. (Bruce Sidlinger)
          The valet code can be 11111 (or some other universal standard
   valet code). Holding down the "5/6" key while in park will
   engage this mode. Restarting the car with the regular code
   will disengage it. (Chris Yoder)
     12e. Move the "coast down" button to somewhere on the steering
          wheel. This way one would not need to take ones hand off
   the steering to change the re-gen mode. (Margaret Cheng)
     12f. Add two, 3-position, steering-wheel-accessible thumbwheels
          to provide comprehensive control of pseudo-inertia and
   pseudo-friction, as follows:
   1. "stationary behavior selector" (left thumb):
       up     (latching) -> creep (in "R" or "D")
       center (latching) -> free rolling
       down  (momentary) -> active station_keeping mode (hill hold)
   2. "deceleration behavior selector" (right thumb):
       up     (latching) -> free rolling
       center (latching) -> coast down
       down  (momentary) -> maximum regeneration
   (Bruce Sidlinger)
     12g. The power door lock buttons are not very well placed or
          ergonomically friendly. They are not marked U and L like most
   other power door lock buttons, and they are too far back on
   the door. (Tom Dowling)
     12h. Autolock and unlock on the power door locks. Doors lock
          when car is placed in drive or reverse; doors unlock when
          vehicle is turned off. Some cars refine this a little by
          also requiring the brake to be unengaged. An enhancement
          would be a method of tailoring the operation via the
          keypad, so that those who did not want the automatic
          locking or unlocking could turn one feature or the other
          (or both) off. (Tom Dowling)
     12i. The set point of 66F as the dividing line between making 
          heating and cooling available should be driver programmable
          to accommodate individual preferences or local climatic
          conditions. (Tom Dowling)
13. Charger.
    13a. Convenience charger redesign - Move this into the car under the 
         hood so that charging from 120V just requires plugging an 
         extension cord into the car. A male 3-prong outlet could be built 
         into the car to allow a standard power extension cord to be used 
         as is done for electrical tools such as hedge trimmers. This would 
         eliminate the following problems:
         - Charger power cord is too short for most situations.
         - The charger needs an extra cable lock because it can be easily
           unplugged and stolen.
         - Extra work required to remove and stow the charger.
         - The charger takes up extra room in the trunk.
         - The fan noise of the charger would probably be less obvious if
    it were buried under the hood. (Kodama)
         Currently the location of the GFI on the charger might leave a long
         extension cord unprotected. The safest approach would be to put an
         integral power cord on a reel in the car, with a GFI-equipped 
         three-prong plug at the end. (Geoffrey Sommer)
    13b. Install a pair of channels or rails at the front of the car, so
         that the convenience charger can slide into them, with a hole
         for a padlock. This would keep the charger off the ground, out
         of puddles, and make it easier to use and keep safe. (Tom Dowling)
    13c. Have the car send a message out via a pager, or cell phone, to 
         let a person know when it is not taking a charge as intended.
         This will prevent an unpleasant surprise to a driver returning
         to the car after some time, believing it is charged, and finding
         it was just sitting there idle. (Sharon Hoopes)

14. HVAC
    14a. Better internal (ventilation) air flow. (Kodama)
    14b. Ability to direct floor heat to driver's side only, to
         warm the driver's footsies faster when there is no
         passenger. This could be done by toggling the floor
         air button, with two lights above the button -- L and R,
         or Land BOTH or a three-way toggle L, R and BOTH. (Tom Dowling)
    14c. Allow the air conditioner to run at all time while connected
         to the charger. (Many)
    14d. A fully automatic climate control that will control fan
         speed, pump speed and the selection of fresh or recirculated 
         air for the optimal setting to achieve a preset cabin temperature.
         with manual override on all parameters. (Many)

15. Displays & Indicators.
    15a. Alphanumeric display - Ideally a generic CR-type (or LCD) 
         display could present more information to the driver and 
  lend itself to incorporating electronic maps for the future.
    15b. Expert Mode.
         An optional expert mode just like some software packages have.
         The car could still be delivered showing "idiot bars" but
         techies could type in a code and then get numerical readouts
         of various parameters. (Bruce Sidlinger)
    15c. Analog speedometer - A user configurable choice between
         the current digital speedometer display and an analog one.
         (Gary Lindgren)
    15d. A way to display the outside air temperature. It can be
         implemented by a momentary override of the range display.
         It could be a separate button on the console or could
         display for a few seconds any time any of the HVAC 
         buttons is depressed. (Tom Dowling)

16. Windshield wipers.
    16a. The windshield fluid spray pattern needs to be improved. The
         lower part of the windshield does not get cleaned, especially
  when the car is in motion and the airflow is carrying the spray
  to the top of the windshield. (Kodama)
    16b. The way the windshield wipers tuck away under the lip of the
         hood makes it difficult to wash the exterior windshield.
  A "cleaning" wiper switch position which moves the wiper arms
  out fully would be handy. (Kodama)

17. Creep feature.
    Replace or augment this with a mode which holds the car motionless
    no matter what kind of slope the car is stopped on (e.g. uphill or
    downhill traffic lights). (Kodama)

18. Extended range trailer.
    Additional batteries installed in a trailer that can be towed 
    by the EV1 for those occasional long trips. During regular use, 
    when the 70-90 mile range is sufficient, the trailer will be 
    left at home. (Avi Hershkovitz)

19. Onstar.
    Have the GM "Onstar" system as an option available on EV1. 
    (Linda Nealon)

20. Public chargers.
    20a. A longer cord that will enable more cars to reach the paddle.
         especially when the parking spot is blocked. (Linda Nealon)
    20b. A regular 120V socket (with bicycle-type cable lock place)
         below the charger so desperate EV owners, finding all of the
  charges in use, could still get some charging using their
  portable charger. (Dave Kodama)

21. Emergencies.
    An "emergency override" button to be used when the car losses 
    power in a dangerous situation. The driver then can chose to
    damage the batteries but save his/her life. (Dave Kodama)

22. Seats.
    22a. I wish I didn't have to use the lever to put the seat back 
         back to the normal position when it is tilted forward. Very 
         awkward to have to use two hands, especially if you've just 
         fetched something out of the back. (Tom Dowling)
    22b. Move the seat adjusting mechanism farther back under the seat.
         Currently, it is just fairly far past the front edge of the
         seat, and it is too easy to hit it with your foot as you
         enter the car and the seat shifts position. (Alec Proudfoot)

23. GPS.
    GPS in car with software that is able to display the location
    (or direction to) the n closest chargers. Location updates would
    be received via paging network?. (Dirk Harms-Merbitz)

24. Charger timer.
    Integrate the timer into the charger, or the car, instead of using 
    the clunky "water heater timer" and all the additional wiring that
    come with it. (Tom Dowling)

25. Windows.
    Add a defrost element to the side "wing" windows. They get fogged
    up and it makes driving in the rain difficult. (Chris Yoder)

26. Cup holder.
    Redesign the cup holder. The existing cup holder cannot prevent
    the cup from falling and spilling its content on the keyboard,
    in the event of an abrupt stop or sharp turn. (Margaret Cheng)

27. Trunk.
    27a. The trunk lock should be changed to a regular lock, without 
         the "valet" feature that disable the inside trunk release. 
         The valet feature is very seldom useful with the EV1, and 
         it's all too easy to bump the valet slide into the valet 
         position accidentally. (Tom Dowling)
    27b. Move the remote trunk release lever to a better location.
         In it's current position it is easy to catch your pants
         on the lever or activate it with your foot when climbing
         out of the car. (Jerry Hudgins)
    27c. Omit the remote trunk release lever all together. Use
         the door keypad and/or the console keypad to preform the
         remote trunk release. (Tom Dowling)

28. Lease.
    28a. Remove the 30,000 mileage limit on the lease. (Tom Dowling)
    28b. Remove the 36,000 mileage limit on the warranty. (Tom Dowling)
