Smallest pothole would trigger the ABS for 1/10th of a second. This completely disables regen and it's all friction breaks. Transition is not smooth as they put emphasis on stopping the car.
My experience - shared by others - is that it feels as if
the brakes have stopped working for a large fraction of a second when braking on rough roads. That may be illusory, but it's an unnerving illusion.
+1 and even when I know it's coming I get a lump in my throat when I feel what I think is the breaks releasing when trying to stop.
I use a particular freeway exit several times/week and it always gets me. It's coming off a 70 mph freeway where I almost always have someone on my ass(most people like to do 75-80, I usually do 65-70) down a somewhat steep off ramp and towards the bottom of the hill is a stop light and right turn lane where all you need to do is slow down and merge with any traffic that might be on that cross road. Right before and into the turn lane there are several rough areas in the pavement that are impossible to avoid, to make matters worse they continue into the curve. My latest strategy and it seems to work pretty well is to break somewhat hard right before the bumps/curve and then let off the breaks as I go over the bumps and into the curve. Doing this I don't get the feeling of the breaks giving out and it's a overall better feeling
