LA is a big place, my guess is you are judging it based on your living experience in one particular area, I am guessing next to the beach (because of the surfers and 70 degree weather). If you lived in the Valley you would know the weather can get crazy. If you lived in the westside or northeast, you would see hipsters everywhere. If you lived on the eastside, you rarely encounter a surfer. If you lived here long enough or don’t have a car you realize that the public transportation is great (especially to avoid traffic) and is used by many. With that said it looks like you are enjoying LA and I welcome you to enjoy the rest of it.
