Hmmm.. how about you get a car with a real engine in it instead of two squirels? 8-) Just kidding. The etiquette is really to keep right except to pass. If you're not passing somebody you should stay out of the left lane (is somebody is looking to pass). I hate when people stay in the left lane and don't allow me to pass. That forces me to pass on right which is not desireable.Doesn't matter what car you're driving.btw-- I always let people in and try to be courteous. What I really hate though is people who don't know the meaning of a Yield sign (especially those on freeway exit ramps).
