That can be a problem. You have clusters of cars riding bumper to bumper. Better if lanes on right traveling faster.

Better if lanes on right traveling faster.

Exact opposite of how we drove when I lived in Europe, and high speed driving there was a lot safer than in the good ole U.S.A. Everyone there knew that you stayed in the right lane until you were passing. When you got out in the left lane you did your business and pulled back in with no dilly-dallying. There were no "left lane vigilantes".
