to be fair to the big-guys, often it's because they've already done it.

Re-generative braking has been used in different guises in British busses for decades. The most common one is pretty much what was described, the wheels push hydralic pressure into a reservoir when braking and release it back out when taking away. ( What might be clever with this suggestion given is if it were built into the ENGINE ) Electric's been done too. But, the scariest one was in the 50s (IIRC) when they stored it in a flywheel ! I just had visions of this few hundred pound wheel spinning at 20Ks breaking free and mutilating everyone in the bus - I was a kid at the time
