It bugs me tremendously when I have a truck or car on my tail when going 52 in a 50 mile zone. I even had a mass highway truck almost on my bumper while I was going 40 in a 40 zone. I personally try to keep it within 2-3 mph of the actual speed limit because it gets me the best mileage and I feel most in control of the car. I could understand people's frustration when you get drivers going 10 miles slower than the speed limit, but there seems to be little tolerance for those of us going the speed limit. Personally, if people want to speed and waste their money, it is fine with me, just don't crowd my tail when I am going the speed limit.
