Driving in L.A. is a nightmare. The exit lanes are not well marked. When you finally reach your exit, you realize that you have to exit left instead of right (or vice versa) and must cross 6 lanes of speeding traffic which is impossible. Then you have to drive to San Diego before you can turn around. By then, you've been routed to Palm Springs. Periodically you exit and ask somebody directions. Nobody knows where anything is. Most of them don't speak English and just arrived from the Island Nation of Zaza or some other place you never heard of. Finally you conclude that you can't get wherever it was you were planning to go; so you just drive out into the desert somewhere, stop the car, and see if you can recover.
On the other hand, I'd hate to be in the tunnels when The Big One hits--or even a Little One.
