I just ran across this on youtube.com. Apparently a bunch of people used the Grand Theft Auto San Andreas game with imported skins of various vehicles to create an abbreviated version of the 1971 version of Vanishing Point. It's well worth watching, if for no other reason than the fact the Challenger is the best computer version of the car I've ever seen. The video is in three sections. Here's a link to the first. You can easily find the other two when you watch this one.
