I've only heard that driving in LA is AWFUL and that public transportation is non-existent

Never having been to LA, but having a burning prejudice against what sounds like their reputation for THE CAR IS KING, this is pretty ambitious!
Which means we should try to beat them.
Having driven, walked, and biked in LA (with the latter two options being a joke for transportation at the time), I'm really impressed by this. I have my doubts that it will make a dramatic improvement, though. On my last trip there this past March, I saw a fair number of bike lanes and bikes on the streets, but they didn't seem to make the streets much more friendly.
They've got to start somewhere, though, and that's a pretty impressive plan.
Driving in LA is GREAT - its the commuting that sucks. What is great is that everything is on a grid, so if the freeway is jammed, its easy and logical to hop onto surface streets.
And their transit system is improving - I think it's called the red-line. Might not be as extensive as NYC's subway system, but way better than Pittsburgh's.
I would hardly call it non-existent. There are trains, light rail, bus service, carpool lanes. The problem seems to be that people have pretty severe bus allergies in LA.
