To test full size cars the test section of the tunnel would have to be >20' square, the rest of the tunnel, which should recirculate on itself, would be bigger, you would need 1200-2000 horsepower, and it wouldn't be in a suburban location because it would be as noisy as a dragstrip.

All the above is In My Humble Opinion, of course. Otherwise, a great idea.
