The tires wear the same amount here because either way, the car decelerates by the same amount at roughly the same rate.

No, it doesn't.

With the ICE car, if you want to go 55, you might accelerate to 57 and then coast down to 55 without using brakes.

With an EV you might accelerate to 57 and then brake to 55 when you let off the accelerator.

Tire wear is a function of how often you use your tires to slow down the car. With an ICE car that's every time you hit your brakes. With an EV that's both brakes and regen. An EV's time spent braking or regenning is more than the time an ICE car spends braking.

Someone could design an EV that behaves the way you describe, but aggressive regen sells better, so no one does.

No one with more than a few miles of one-pedal driving would do this; it’d be highly unpleasant.

What actually happens is you remap your pedal inputs: all the way off is braking, somewhere in the middle is coasting. Your brain will do it automatically and OPD is far more pleasant than two-pedal driving after a trivial learning curve.

No you don't; in fact you can't. Letting off the accelerator enough to apply regen is going to take far more than 2 mph off your speed.

If you want to drop from 57 to 55 in an EV its done the exact same way you do it in an ICE vehicle: you coast.

Coasting wears your tires too. By the same amount.
