I don't have a problem with them passing me, speeding or not. It's those drivers who drive in the left lane even though they are NOT passing anyone. And, they won't move out of the way of anyone behind them.
We do have our share of speed demons who leave 10 or 15 minutes late and try to make up time in traffic. Cain't be done.
One more thing about the 18 wheelers, is they seem to have supercharged engines in every truck, as they all can take off from a traffic light and stay ahead of traffic. </sarcasm>
