I always forget that people are smart enough to horse around in traffic. I know how amazing some people are at driving. I remember driving down to uhh.. somewhere south, south of Atlanta but still in Georgia, and I live about 45 minutes north of Atlanta + I went during a 75, 85 lane closing.
About five times on that trip, someone attempted to merge into my car, with two of those people actually looking up when I'm blowing my horn and they still keep merging into my front bumper. I love people who look into their rearview mirror to merge...
