I thought I posted a reply? Our rules say we must sit astride a saddle, steer with handlebars and not be enclosed. The Diablo, Exocet etc are clearly 3 wheel cars. Polaris are trying to fudge by not having a roof or doors. We can have an open Delta trike even homemade with seats for 2, or a factory built tadpole only if it has a saddle, handlebars and no top.I know nothing of the vehicle laws north of the boarder, but if there is a way around the problem someone will find it sooner or later.
