Actually- i want to come in say that besides china, i've got probably the biggest idiots surrounding me on a daily basis.
1- SF isnt big but its definitely a "city" with a downtown, highrises, buses, taxes, a$$tons of pedestrians, etc. as well as tons of STEEP hills and amazing views. which means....
2- people are often totally frickin clueless to where they are going, supposed to go, not supposed to go, or just want stop in the middle of god damn traffic and stare at the sights, the homeless, the gays, the trannies, etc. etc. etc. thats because..
3- alot of folks in SF dont drive. or do it as little as possible. so we most of the drivers here are the tons of folks from the suburbs/bridge/tunnel and they are intimidated by the cityscape, or WAY too cautious due to the intimidation and just get in the damn way and clog things up. which is way worse in its effects because....
4- every other god damn car is freakin uber or lyft. or a ******* robot self driving car. the robots i have a tiny bit of patience for as they will be carrying my old ass around someday. but the uber/lyft drivers? OMFG. they come from sacramento. central valley. even LOS ANGELES. to drive in SF for 2-3 days and then drive home. insane. and while the bridge and tunnels might at least have been here once or twice before, the goddamned uber/lyft idiots have NO idea what they are doing.
looking for an address? drive. stop. drive. stop. drive. stop. blinkers? why would i put on my blinkers so people will see i'm stopped/looking to park?
missed your turn? pull a U in the middle of a two lane street. with buses. and taxis. and pedestrians.
didnt hear Siri with your driving directions? stop in the middle of the street/intersection or wherever and just stare at your phone for a while. push a few buttons. then wait for it to reload. no biggie.
your town doesnt have motorcycles or bicycles in the street on the regular? then you should definitely slow down to 5mph and WAIT for the old fat chick to pedal her ass up to the intersection.
you dont have at least 5' of clearance on either side of your car? well, then just stop and wait for the truck/bus/taxi/fedex/bicyclist/homeless/motorcyclist to give you your 5' of clearance. dont worry, the rest of us will just wait.
but the BEST PART? "man, SF is crazy. i should have just taken the subway"
NO F"ING SH!T SHERLOCK.
