If you see a guy in a company vehicle driving crazy call the company up and tell them. Trust me they want to know and 90% of them will take action.

But also Try driving a work van and see how many rich people take offense when you pass them. It's mind boggling. Lexus, Mercedes, BMW, tesla, etc. I have my cruise control on at all times on the highway and the amount of leapfrogging that occurs with these drivers is nuts.. It's like they can't stand that a blue collar worker passes them. Never have this issue with lower end vehicles and trucks.
