Would startle the hell out of you if you saw one on the road I bet!
There seem to be a few 'car things trying to be bike things' coming out these days.
Related yarn actually: I parked up in the MOTORCYCLE parking at the local mall and as I'm taking off my gloves, some 'cool dude' in a singlet, baggie shorts and sandals rocks up on a canam trycicle with VERY loud pipes. He then proceeds to 1000010 point turn to try and park next to me in the MOTORCYCLE parking bay! Obviously theres no way in hell he's going to fit as the thing is probably bigger than a smart car.
After a few attempts he gives up holding up the traffic and parks in a CARPARK, which the trike fills rather easily on it's own I might add.
At least the item above has a roof. I think I would like to try one to see how it goes, you wouldn't catch me DEAD on a Canam though!
