I drive a diesel. Back when I had a regular freeway commute, I would regularly come to a complete stop at the end of freeway exits without touching the brake pedal, just for fun (last few km/h I used the handbrake). And one time when I was randomly pushing a little too hard on the brake pedal when I was parked, I burst a brake line somehow, and I ended up driving 20+ miles to my mechanic on busy city streets with no brakes, safely.

I doubt regenerative braking is any stronger than that.
