It happened again. On a steep down slope , after a small bump, only the rear tiers skidded . So it looks like due to 'keep it simple' , the brakes are applied only in rear.

FWIW, going downhill, the weight transfer to the front during slowing means it is much harder for the front wheels to lock up versus the rears. Throw in the antilock logic, and things get a bit more complicated. Obviously, though, regen only applies to the driven wheels, the rear on an i3. Now, some Teslas have all wheel drive, so they can do regen on both axles. Don't know that they do, but they could.
