If I didn't live the currently frozen hellscape of rural Alberta I'd consider it. Or if I moved back to inner city Edmonton.
Alas due to almost 80 years of right wing rule (with the exception of 4 glorious spins around the sun under a social democratic leader) the roads here eat cars. Oversized loads + frost heaving/thawing cycled leaves the roads eating suspensions. How do I know? I own a Smart Fortwo cdi that gets 50 mpg but has gone through 2 sets of shocks thanks to potlines... I can only imagine someone trying to play chicken traffic trying to commute on our crap roads or sidewalks.
Still a good idea though especially for last mile solutions for most of the world!
