If you live in LA you'll need to go over at least one highway.
Edit: ITT many Americans telling me of how walkable and great their towns are. I'm happy for you but comrades, I've been to the US once and that was on a trip I won in high school so don't expect me to know the zoning plan of Providence, Wisconsin Pop. 235'489. I don't really care how lovely your city with two buslines is. For every Seattle or Chicago there are 34 Cincinnatis, Houstons and Las Vagases and approx. 234 exurbs and suburbs.
I'm in an area where theres a lot of apartments built over very useless specialty stores and expensive restaurants. So you get the "walkability" look without anywhere good to walk to and highways all around. I could see the mall but it'd take an hour walk.
I recently moved to a place where I can walk to a corner store that sells beans, onions, rice, and other basics. As well as a deli that sells a bunch of cuts of meat. It's been life changing.
