I agree the consumer will
I agree the consumer will have the final say and frankly, there's far too many "gearheads" out there (myself included) to give up the wonderful sound of fuel injection and tuned exhaust. And what happens with motorcycles btw? I cringe at the thought of doing away with the sexy bass tones of a Harley V Twin. Petroleum is an ingredient any many consumer products and I doubt the oil boys will just roll over and let this happen. No, I suspect oil
will be propelling vehicles for many years to come.
