Cars are nice for some things, but they don't scale well. The bigger the city, the worse cars work.
Ive never seen my GPS do the sort of gymnastics it did when driving to Long Island during rush hour.
Of course, NYC is #2, so not much better. But at least there you have a viable option besides driving.
Weather I'll give you, how many miles of bike lanes are really being built though? What's the ratio between bike lane miles vs car lane miles in the city? What percentage of the bike lanes are protected vs unprotected? Are there any protected intersections?
I don't dispute that LA is taking biking more seriously, but it'll be a loooooong time before biking is even a second class citizen like walking in LA.
