Note that I am not wanting to "start something" in asking.
But a MC riding group I belong to had somebody ask if they could drive their Slingshot on one of the group rides. The group seems divided in their attitude. We do have trikes and Spyder's in the group and a custom built VW trike (1 seater).
MHO: While I think the Slingshot is a cool looking vehicle, it is very big compared to a MC trike - as big as a Mazda Miata (save for overall length - 4 inches diff.) And bigger than the VW trike. It may detract from the idea of a MC riding club.
I would appreciate your thoughts on this question to allow the Slingshot? (Or are people picking the fly feces out of the pepper?)
