if pedals resistance to be pressed to the floor/wall is too less, one can go over bumps or daydream thus end up not energy input vs movement keeping momentum consistent on monotonous roads, which is for efficiency over many iterations, if pedal resistance is too much its more tiring to hold pedal over longer trips. this could be fixed with cruise control assuming the software’s knows when car needs to slow down b/c it cant carry momentum at maybe even a slight turn
if not, there can be a touch on screen (or that modular programable optional switch concept from old forum) to ECU lock pedal input, then when wanting to change speed, the screen will show how much to push the pedal to maintain momentum before signaling that the driver in back in control. this also can be used for switching out of auto pilot type thing.
in old forum, there was version of this that mechanically locked and unlock pedal in place, which would prevent need to be distracted by a screen that’s hard to be careful with enough to modulate the right graphics especially on bumpy ride over bumpy parts of road. it used toothed pulleys and chain and a sliding door lock style pin to lock into side of holes.
