Might be something you do once, just to say, "I did that".
Oh wait, someone already did that.
I think it would be more fun if the wheel spun continuously and people had to time it just right then...LEAP onto a passing car.
Indiana Jones music could play in the background during the leap!
Still, ride it once, then get back to the theme parks, I say!

I really don't get this. In London there are plenty of sights to see. On I Drive what are you going to see, swamps? Sound like a loser idea to me.
