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.
Tbf walkable cities in USA are the exception. 90% of the country is designed around cars, even large cities. Most of Europe really beats us on this but they didn’t have automobile industries meddling in the creation of their infrastructure like we did.
