Anywhere you go you are gonna meet crappy drivers.
In the Bay Area, we like to think we're polite but when I'm in LA I think that they're DEFINITELY more polite. Probably because they are used to driving in traffic.
Whereas, in the Bay Area, people will drive on the shoulder to get into the exit, try to change lanes in traffic WITHOUT their blinker on, and carpool lane cheaters suck. Also everyone here lives on their cell phones, and even with handsfree sets they still get distracted. Also, there is absolutely no freaking money to fix the degrading highways and when they do fix them, they seem to fix the parts that weren't broken.
I admit I'm an aggressive driver. I won't honk my horn at you but I will yell and scream at you from the safety of my car. And if you dare cut me off, lemme return the favor for you. With a smile. =)
