> so the mechanics failed but the electrical part still worked.

Electric cars use brake-by-wire. Push on brakes, computer processes signal, computer applies brakes. Glitch somewhere in that system

Not for braking past a specific point, it's just regular hydraulics once you get out of the range for regenerative braking.

Hmm, interesting. I didn't know that

Brembo is working on an all-electric braking system where the calipers are actuated by a servo system but afaik this has not been released yet and even then you'll need to meet or exceed the kind of performance you expect from regular hydraulic brakes to ensure that in an emergency situation that car can be stopped fast enough, which regenerative brakes can not normally provide (if only because the electrical system could fail).
