They need to change the laws to make it an easy ticket. Right now, I think the closest they have is "impeding the flow of traffic", but that one is easy to beat it court if you were going at the maximum legal speed. Many people feel better about themselves by personally enforcing laws they believe in and don't realize they are humongous d-bags that make the roads more dangerous for everybody.
I tried using the QEW HOV lanes last Sunday but the regular lanes were moving faster because of a dodo going exactly at the limit in the HOV lane.
