I visited Santa Monica (basically LA unless you live in LA) several times and walked almost everywhere, only taking a Lyft when I really wanted to go across town (the Blue Bus comes eventually, but it isn't fast). Air quality was fine and there was a 4-mile beach to walk on if you wanted to really Walk. I know people who live in Downtown LA and don't own cars. I get the impression there are several parts of LA you can live in without regularly driving, and still have a very normal lifestyle. Not sure about the air quality downtown but my friends didn't complain about it.
