> doesn't do much in cities Incorrect. I drive a lot in the city and I use the friction brakes so little that they start malfunctioning after a week or so if I don't do some hard stops once a week or so to clean up the pad surface. I only use the 'regular' brakes if I am stopping from high speed, quickly, or at the bottom of a steep hill. Probably use regenerative breaking for >90% of all normal stops.
