Interesting. One scene showed a car driver actually following the law (which is still in effect, believe it or not): when a streetcar stops in the street, as a driver proceeding in the same direction you're required to stop behind the rear door of the streetcar and stay stopped until the streetcar leaves and any passengers who got off have made it to the curb. Regardless of what the traffic signal may indicate. Granted, there aren't many places (none in Sac, to my knowledge) where that's still important, but it could appear on a DMV test...and how many drivers in SF actually do that? Revenue opportunity...
