Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

I'm really not a fan of everything being computer driven. Like, anything else I'm not too worried about, but please just let there be a mechanical connection between me and the vehicle stopping and going.
As a car enthusiast myself, I appreciate your adherence to the OG throttle cable dogma, but: how would you propose EV accelerators work, in this case?
Unless you’re talking about introducing a physical clutch to the car that’s controlled by a traditional pedal+master/slave cylinder+clutch and flywheel, that’s not a thing you can do. And (as much as I would ADORE an MT EV), the mechanical efficiency hit is simply not worth it. You’re probably talking about sacrificing double-digits of power and range efficiency (not to mention weight penalties) if you were to design an EV like that.
There's gotta be a different option. It's an engineering question, I'm not an engineer so idk but there has to be some option that can introduce a "switch" or clutch without too much detriment.
You could have the accelerator pedal physically move a variac (variable auto transformer) to directly control the voltage going to the motor.
Alternatively, there is likely a way to directly set the PWM using an analog sensor, instead of interpreting the throttle sensor output through a more complex software stack that could introduce potential errors.
