Since I live in San Francisco and work in San Francisco I obviously take Muni to work since there's nowhere to park at my job that doesn't cost $18 a day. So I never used to drive that much. Just on weekends, pretty much. Like, literally I would not enter my car M-F unless it was street cleaning.
Now I take my offspring to day care in the mid-Sunset area, so I drive every day. It's been an eye-opening experience. Everyone is a terrible driver.
1. For the love of all that is holy, USE YOUR FUCKING TURN SIGNALS
Why are you stopped in the middle of the street? Have you died in your car and now it just sits there, unattended, while your body rots into the seat? No? You're waiting to turn? Your car is almost certainly not a pre-1939 Buick and thus is equipped with a mechanism designed to let others know your intentions vis-a-vis turning. FUCKING USE IT.
2. How Stop Signs Work
It has become apparent to me that most drivers believe that Stop signs work like this: "I see a Stop sign. I pause briefly, then continue on. It matters not if there are other cars at the intersection, in the general area, or anywhere else on Planet Earth. I have paused briefly and will now be on my way."
This is not how Stop signs work, you maroon. Print this out and tape it to your dashboard:
3. Green light means go
Why are you just sitting there? Depress the accelerator pedal. The odds of the North American Plate suddenly lurching to life and moving under you so as to propel you through the intersection without you operating your car are vanishingly small.
4. Double Parking: Is It For Me?
Double parking is mostly OK if you just have to run in for a second and it's a fairly wide street so the rest of us can get around you without too much trouble.
DO NOT DOUBLE PARK:
a. Anywhere near an intersection.
b. Anywhere, at any time, on Fell, Oak, Gough, Franklin, Turk between Van Ness and Divisadero, any of those little tiny streets in Bernal Heights or those alleys in the Mission, or anywhere else you're going to royally fuck up traffic.
c. When there's a perfectly good parking space right there! What the fuck are you thinking? Take the 30 seconds and park! Christ!
5. There is no point in tailgating. It almost never makes the person in front of you go faster and you just look like an asshole.
I'm sure I've forgotten some big ones. Enlighten me in the comments if you wish.
