Then again, the driver could be still hard braking. I have heard some people say that they frequently use the brakes to regen energy to extend range. Makes no sense whatsoever.
Heavy regen is not free energy, it is exactly the opposite. Yes, it recovers maybe 55% of keinetic energy compared to an ICE car that throws away 100% of kinetic energy. But still you are wasting fully HALF of the battery energy used to get to speed. But if the car is not coming to a stop and the driver is only applying the brakes to slow down because she was otherwise going too fast for traffic and conditions, then that is no free energy, it is wasted energy. Sure it is less waste than an ICE, but it is still *very wasteful* compared to coasting to preserve ones kinetic energy instead. Just a possibility. This report claims 55% recovery during regen: http://proev.com/LLPgs/LLei0005.htm Again, any use of regen that is not for the purpose of coming to a required stop, is throwing away 50% of the car's kinetic energy, and is an indication that the car is tailgating or generally speeding above the average speed of vehicles in his lane (also wasting energy).
