Most car seats are improperly installed. If you have one, get its installation checked by a professional.
In the SF Bay Area, you can have CHP check it for free. The full-time job of the officer that checked ours is investigating accidents where kids in car seats died. Almost all the child fatalities around here are due to improper car seat installation.
We had it dangerously wrong. Before the appointment, I read the manual twice and spent something like 60 minutes installing it. The seat used the latch system with a top anchor, it was a new car and we had a top-ranked car seat. All the straps were connected up correctly. During installation, I sat on it with all of my weight, pushed against the ceiling of the car with my back, pulled the tightening strap until it felt like it'd break, and then pulled harder. The straps were still too loose. I'm not small.
Our last car seat had a failure mode where one of the latch straps would just self-release every 1000 miles or so. I'm not sure if it was user error or not. It happened twice.
After that experience, I think part of the certification process for car seats and cars should involve proving that the majority of people that have never installed a car seat (i.e., first time parents) can get it right on the first try without reading the manual. The test group should include people with physical impairments, and should include at least a dozen popular car models going back a decade. (Car certification should be the same, but with multiple car seat models.)
100% this should be mandatory reading for all new parents.
Since you mention only SF, for anyone else who happens to read this, just go to your local Fire Department. They will 100% either know how to secure it for you or guide you to the correct place.
