Because, as you said, the only place with competent public transportation in this ENTIRE COUNTRY is right there in New York City.
I don't live in NYC. I wouldn't live there if you paid me! I don't mind riding the bus, but most bus drivers here are required to treat their passengers with contempt, or risk getting fired. It took me 2.25 hours to ride the bus to work, and only 25 minutes to drive it on the expressway. I wasn't stuck in traffic, unless I was riding the bus...
I live in Las Vegas.
