What about a motorcycle's range? Are these vehicles not ready for prime time?
Of course not. Motorcycles only fit the needs of a minuscule segment of the population, they are not and never have been a "prime time" [equivalent] type of vehicle. They also get poor mileage (for their mass, especially, but many of them actually get poor mileage on the small car scale now, since small cars have come so far) and they have high pollution except in the few places where catalysts are mandatory. Even then, you can expect more pollution per gallon burned.
