OK...I just broke 1000 miles on my car yesterday (3 weeks ownership). Noticed there isn't any dark brake dust on the wheels like there was when I had my old A6 or any other cars in the past. I know that the hybrids have "regenerative" braking but how does that work? Does that mean brakes get new pads like every 100K miles or what? Thanks in advance. I do remember my salesman telling me it's compared to a ceiling fan when you reverse it from forwards to backwards.
