I would more then likely feel differently about it, if I lived in Oshawa in the Durham area, as they have bigger and better paths. Guelph does not seem to have the same for paths. No paving, mainly crushed stone.
I'm sure I'd use them if I was on a much cheeper MTB, but I also don't want to cause a fuss as our local by law states "No Motorized" on all signs.
Car drivers here also for the most part seem to have no issue moving around us scotters. There are alot of us out here now and more comming this summer.
