I used to own a fleet of Mercedes Sprinter vans, before retirement. Those vans had no problem keeping up with traffic speeds, yet you will always get the idiot, who just has to get in front of the van. They will risk life and limb to do so. Morons.
I know how you feel. I have a Tacoma, my Toy Taco. I will be tooling down the highway, when I have to pass a Dodge Ram, (always seems to be one of them,) a few miles later, they always come barreling around me. I don't mind, except, a few miles down the road, there they are, puttering along, and I have to pass them all over again!
