I hope I'm not coming off too much as a hippie, but given the problem being running out of space to build roads on, fossil feuls becoming more expensive, and the decay of the envirement, in general, ride comfort, and having to sit in the rain, is one of the lesser problems I'd worry about...
And, besides, they have designed motorcycles with a canopy, and heating, a car-like seat, and all that stuff... Soo if you're into that...
But yeah, transport is a big problem in general...
