Fry's at one point carried a laptop stand that hooked onto your steering wheel. I always found it amazing every time I saw it. I havn't seen one in years, so perhaps common sense got the better of someone.

That being said, try checking your local police force? Most of the cars I've looked inside recently have a laptop mounted for the driver. I've never paid any attention to the asthetics, but I doubt they do either.
