Your listing LA as a non car-centric city? You must be joking. LA is the absolute antithesis of a non-car centric city. Maybe you missed this?

And maybe you haven't been to NYC in a while because although there is lots of mass mass transit, that does not make it non car-centric. It most certainly has a car traffic problem. Just because you don't have to own a car does not make a city non-car centric.

If you look at the inrix score care you will LA is number 1 for traffic and NYC is number 3.
