Hybrid is still in early days, once otherwise wasted (via braking, dwnhill, coasting) energy storage has been compacted enough it will find its way into all modes of transport...if you try to drive a fully loaded lorry without braking as much as possible but slowing down on the vehicles exhaust or other retarder you soon begin to realise just how much energy is being wasted, if, as in hybrid, it could be collected and re-used then all sorts of possibilities arise.
Hybrid may seem expensive now, though i believe Toyotas version are already cost effective for many, but give fuel costs another 15 years and we might all be buying into hybrids or other fuels of one form or another.
BMW and the like will catch up, they and others sell what people want of the moment, and recent years have seen high cost German cars the ultimate image purchase...once BMW and their competitors jump on the bandwago, and the image conscious and/or fashionable celebs start buying in then Hybrid will be the new must have.
I hope Toyota are selling their technology at a good mark up.
