tips on traffic:
if you're gonna be driving during the week leave before 8am - if you don't then you should wait until 9:45 or 10 - this isn't universal, but if you're going anywhere >10 miles that's what you'll want to do.
in the afternoon same rule applies but its worse 4-7pm are the times you'd prefer to avoid - whatever you do don't end up on the westside (SM, Venice, Culver City, etc) and then try to go east in the afternoon. Leave by 3:30 or you're effed - same goes for the 405 north at that time but its usually a bit better before then.
Ubers are everywhere and are there within 3 minutes 99% of the time, Uberx is especially cheap.
