Accidently drove into Mexico huh?
The road is like a freeway - one way, with barriers on each shoulder. If you miss the last U.S. exit, you can’t turn around, back up, or otherwise reroute. If the last exit was closed for construction, he was in trouble. In retrospect, it would have been better to just shut down, right there, and let the Calif. Highway Patrol tow his vehicle to a storage yard.
