All cars need real old fashioned mechanical brakes on all 4 wheels, EV or not, AWD or not, and all mass produced EVs have them, just like ICE cars. Regenerative braking is only for relatively light braking, only works when the battery isn't full, and isn't as reliable as a hydraulic braking system (which include independent redundant circuits). An EV cannot do an emergency rapid stop with regen alone.
On the plus side, if you have regenerative braking, the brake system wears much less.

- ajross 3y agoThat's pretty much exactly right. Once you get the feel of one pedal driving you really just never touch the brakes except in genuine evasive maneuvers, or occasionally to finesse a precision stop (pulling up to a wall in a garage, things like that). They get almost no regular use.
