Your idea will not work. It is the first thing any inventor worth his salt has tried and failed on. Your dragging a lot of weight around. plus the energy required to run your other wheels as a generator. Add the losses of transmission along the way, and you will get minimal recovery. In fact, you will likely burn more energy than retrieve in this manner. Making it a net loss. You would be far better off trying to limit weight and drag than trying to generate electricity by using electricity. Though the use of generating properties during braking is a good and novel way of recouping some usable/plausible energy.

Parasitic drag is your primary opposition. Maybe you could take your ideas into space. Very little drag problems in zero oxygen/gravity in outer space. Go on, I dare ya'.

One of the cooler ideas I've seen is the use of rising and lowering ocean tides to fill huge reservoirs. As the tide rises, the water rushing in runs generators. when the tide runs out the generators reverse and create energy as well. It is elegant in it's simplicity. And the closest you will ever find to a free ride. Charge your electric car from this, and there's your perpetual motion!!!
