Other manufacturers have tried to accommodate the old muscle memory issue of letting go of the accelerator by having the brake pedal be the main or only control of regen. At least a few years ago. I think most have switched to one pedal driving. Having to use two different pedal to accelerate or slow down is just an old unnecessary burden. It makes driving in traffic less comfortable. Driving an EV without regen, which is what you do if you eliminate it from the accelerator pedal, you are getting 20% less range. Yes I have tested this *extensively* using CAN bus data in all three of my Tesla vehicles. It is 20% in typical city driving.
I was a very early adopter. Had an EV in the 90s, got my first Tesla in 2014 and loved the tech. I still needed weeks to fully getting used to one pedal driving. It is literally the first thing *everyone* says when they first drive an EV. They don't like how the car slows down when they let go of the pedal. And once they got used to it, it's the thing that everyone loves about driving an EV.
