Yeah we were driving across Texas going to a lake and I was sitting in the passenger seat so I figured I would try out and see how it worked. It did not it freaked out constantly. I think if you had a vibe with a laser tracking system it would actually work but that would be interesting to mount inside of a suburban.
One of my favorite things I ever did was sitting in the bendy middle section of a bus in Seattle which constantly moves while going up and down the hills and playing super stardust HD on Vita that almost got me.
