The obvious solution is an electric Delorean. No corrosion and it can easily be upgraded to Mr. Fusion power when batteries become obsolete.
Most of the time I take the bus to and from University (UBC). On the rare sunny day in Vancouver I take my electric skateboard. Door to door times for the bus are ~25 minutes with the bus, and ~15 by electric skateboard. In good weather it honestly is the best way to get around. And for some reason there's always chicks at my destination.
