Bottom line? Internal combustion powered cars are a bad emissions & fuel efficiency proiisptoon developed into a far better one by technology – lean burn, cat converters, stop start etc. Motorbikes start out with a huge advantage (weight vs. payload, rolling resistance etc) and have been developed almost not at all from a fuel efficiency and emissions stand point. A little progress in this area would literally get us all a long, long way. The demand has to come from riders and that is slow in coming.
