Coming from Texas to the Bay Area, drivers here are surprisingly decent. Sure you get people that don't know how to merge and are impolite. But the degree of rudeness is quite a bit less. I haven't had the displeasure of driving much in L.A. / south California. I have a feeling it's mad max like.
Texas...fml. If they allow splitting there it will be a blood bath I'm telling ya. People are the epitome of selfish a-holes. It's my lane, it's my space and to heck with ya if ya don't like it.
From DFW to Austin, to Houston. It's just bad.
People turn off their humanity when they get in a car. "Oh you want in? Sorry I can't see you right now because I'm pretending to be an idiot...oops was that my gas pedal that closed the gap on you? oh darn. Aww shucks you're stuck in an exit only lane trying to merge on the freeway. Poor bastard, I wish I could help you, but I just can't because I'm in a car and my car and me have a special relationship of f you. I'm going to pretend that you just didn't get in behind me, and definitely won't look at you because I'm not a human being in here."
I was that way for a while in DFW, and somewhat in Houston. I found it just eats at your soul after a while. Years of stooping to that level just kills ya.
Funny thing though if you meet the same people in person, outside of the rude rules of the road, they're much kinder.
oh wait did I imply Texas is the worst? Spend some time in Oklahoma. Maybe the prison is better, but I meant on the highways. I promise you will want to pull off your head and shite in your own neck hole.
I'd rather drive from Jersey to New York City and back every day. At least there, people are not rude, they are just all business, right now. Why aren't you moving through the red light? It's about to turn green you better be on the gas. Makes sense there because if you don't the pedestrians will take advantage of your lax attitude. People to do and shite to see.
