I’ve long wondered why we don’t ditch the friction brakes.

Just have the battery stop charging and report 100% full when it’s only 98% (or whatever) so there is enough capacity for some solid emergency stops in the first few minutes of driving.

Even if you have to resort to the resistor, who cares? It’s not like this is a common scenario

That's fine, until someone charges their cabin up in Truckee and decides to drive down 80 to the central valley (a hour or so drive you can do in neutral).

Regenerative braking also loses a lot of its stopping power at slow speeds. Going from "slowly rolling forward" to "full stopped" takes a lot longer than the instantaneous it is with friction brakes.

You also need some sort of parking brake, and friction brakes do the job nicely.
