an EV for ALL drivers

an EV for ALL drivers

I've been driving hybrids for years and while I like them I think electric is definitely the way to go. Tesla gives a real good option with decent range, styling and power.

Being such an innovative company, Tesla should consider making a model, or an option to allow disabled persons to drive also. I am talking about folks that can get in and out on their own, even if some adaptation is needed. The X comes to mind given that the falcon wings makes getting in and out easier than standard door wings.

How about putting a hand operated throttle/brake stick similar to a joystick in a center console? While a joystick normally controls direction as well as speed, a throttle/brake stick would allow those folks who currently use hand controls to easily transition to a Tesla. You might ask "Why not just install hand controls like on a gas vehicle?" Are you kidding? this is a TESLA! Electronic throttle/brake control should be a breeze !!

Maybe Tesla can replace those accessible vans which by the way, cost the same a s Tesla S.

Just a suggestion.
Looking forward to my test drive tomorrow.

Good idea. It seems that it would be much easier to adapt an EV to be operated by a person with a disability.

Just to clarify, the X's falcon wing doors are for the passengers only. The front doors are standard.

Yes you are correct. But this is similar to the accessible vans where the accesible door is the sliding door (passenger side).
In this case the disabled person would be a passenger.

I don't expect Tesla to market a car that competes with the van conversions, but you never know. VPG Auto did approach that market segment but closed due to not being able to repay their government loan. Its too bad. see

BTW I did take a test drive this weekend and am very impressed with the S!

Joysticks have been considered problematic in cars due to the front-to-back forces during acceleration-deceleration resulting in potential unwanted inputs on the joystick, especially in emergency maneuvers. I defer to any available experts on the subject....

Fly by wire technologies use in aviation would solve any "unwanted inputs".

How does fly by wire remove inertial forces in users hand? That's the "unwanted input" JPPTM is talking about.

How about paddles in steering wheel? Used like paddle shifts in ICE sport cars? Left for brake, right for accelerator.

I don't think you understand how fly by wire works.

Fly by wire can be programmed to ignore inputs and makes proper adjustments to the actual conditions surrounding the vehicle, this needs to be accompanied by sensors, for example, if there is a proximity sensor and you over do the input because say inertia the car will stop or reduce its speed so as not to hit the other vehicle ignoring the extra input, this cannot be done without fly by wire because the input is direct.

Why do you think fly by wire is used in modern commercial and military aviation?

Not yet available in small private aircraft, although probably soon:

I know how fly by wire works, but I'm not sure how you are going to tell car when pushing the joystick is deliberate and when not. Car would need intelligence that rivals human to figure out when action it accidental and when not. It's easier for airplanes.

Is the Tesla currently set up with a fly by wire system using floor pedals? If so switching to a hand throttle sounds fairly simple.

The paddles on the steering wheel are a good option! Many disabled persons who use electric scooters (the first real practical EV's)use a paddle. Usually one paddle is for for forward and the other for reverse. There is no "brake" but you can push the reverse paddle to really slow down fast.

I'm just suggesting that there has to be a solution using electric signals rather than the traditional push/pull mechanical connection to the brake and the accelerator currently available.

thanks for chiming in. your comments are appreciated.

For acceleration it has to be "fly by wire" because whatever you do has to go thru computer to calculate out how much current at which frequency goes to motor. For brakes I don't know how "mechanical" that is, but all modern cars have at least ABS, which is more or less computer-controlled, so I think changing those to steering wheel paddles should be rather easy job to do.

I know handicapped folks who enter a (modified) minivan through the passenger sliding door and then move themselves to the driver's seat from their wheel chair.
