Good grief, give it up on the stupid Radical already.
It might be "street legal" in some states, just like a lot of retarded stuff is allowed in some states and not others. Are there "RADICAL" dealerships? What kind of annual production and sales numbers do they have? Does it pass emmissions? Does it have the proper safety equipment? Well, if the "no's" outnumber the "yes" then there's your answer.
Didn't the Koenigg have some issues a few years ago qualifying for some records because of productions numbers?
