If you don’t mind getting a few extra scrapes on your elbows and knees, then we would strongly recommend you take a look at the Flyrad. We aren’t even sure whether this qualifies as a “vehicle” or not, since it is actually a set of handles which are attached to a motorized wheel, where you hang onto said handle and get dragged around on while wearing a pair of in-line skates. Seems to be the land version of water-skiing, eh, except that there aren’t any sharks to worry about and you won’t leave your life to the mercies of the person manning the boat. We would recommend removing those brakes on the in-line skates lest you lose control of the Flyrad and head down a flight of stairs – the brakes might just be the very thing that does you in then.
