> An electric motor is really good at arresting high rpm movement

I don't think any EV that I've heard of has full-range electric brakes.

There are two interesting kinds of things that I think EVs could use...

brake resistors - if the battery can't absorb the full power of regenerative braking, maybe giant resistors can take the dissipate the rest of the energy.

eddy currents - it might be cool to use eddy currents to brake.
