Cars need [in many cases, for optimum use] back pressure. And as soD said, turbo charged cars do fine with it. Well, more than fine lol

As efficient as the driveline/axle alternator would work, it still slows the car down. This seems pretty brilliant, since the exhaust happens when the engine is on.
