Cool a subject that I can really air my sentiments on. I try not to use my blinkers period, for exactly that very reason, tell an @sshole you need to get over and they'll screw you out purposely. I stay in my lane (which would be why they painted the lines in the 1st place) and only move over when there's plenty of time and distance. Once I find a clearing, I go faster to get away from the one's that have to tailgate each other. I've seen too much NASCAR drafting at highway speeds on the roads, only these people aren't NASCAR drivers.
To be honest, road rage, I've been watching traffic for years and it's getting worse and worse. It seems the shopping is creating even more problems. These people have their heads up their @sses anyways, now they have a reason to go shopping. Even the parking lots are becoming worse than what they usually are. The problem as I see it, cellular phones, dvd players, mp3 w/ video mounted everywhere for each passenger, even the driver. Those people need to realize that if they want to watch the latest video, they need to keep their stupid @sses @ home on their couches. Their job is to drive a car when they get behind the wheel and go from point a to point b.
I shop on-line, have it delivered to where it's gotta be, saves me from actually having to shop with these people, but going to and from work is still a headache though.
