The big difference is a lot of Bay Area traffic is avoidable for people who actually live *in* SF, Oakland, or anywhere that’s BART-accessible. LA is so damn huge that even with the recent improvements in public transport, the vast majority of it is still inaccessible without a car. Which means you *must* drive, which means you must deal with traffic. I am able to pick and choose when I deal with traffic in the Bay Area. Not so in LA.
