IF I was in charge, and I'm not, the ONLY speed limit would be a current law - SLOWER TRAFFIC KEEP RIGHT.
Think about it...if we would all follow those simple four words, we'd all get to where we were going faster than we currently do.
And the dumbasses doing 55 in the fast lane would go to jail and be ****ed in the ass...just sahyin'...
You got my vote. On the autobahn I think it's illegal if you don't move over out of the fast lane when faster cars are approaching. That's the way it should be.
