I was driving at 75 mph on I-25 (Colorado) yesterday {speed limit = 75] and was closely followed by a semi that wanted to go faster. I just tapped my brakes (to activate brake lights) and he backed off, pulled around and cut me off. so much for courteousness and obeying the law.
If there was room for the semi to pass you on the right, why the [bleep] didn't you move to the right in the first place and let him pass? Most states have laws against driving in the left lane and blocking faster traffic. Even if Colorado does not have such a law, what YOU were doing is dangerous and discourteous.
