1. I stopped taking public transportation.
In San Francisco, I did not own a car. The public transportation system was very efficient, and having a car was more of a headache than not. When I moved to Los Angeles, the opposite was true- a car was a necessity. Buses and the Metro existed, but since the city was so spread out it took twice as long to get anywhere with public transportation. Driving everywhere was more convenient, but also a lot more isolating.
