I guess just don't open the gap for them or make it wide enough they don't bust you with the mirror.
The speed limit in my housing area is 10mph. I was going 11mph, and went around a pothole. A guy in a pickup tried to cut off on the right just to go 1-2mph faster. What stupidity. I guess he really had to get home so he could drink beer and watch television. I see it all the time, people that HAVE to pass you, because its a STATUS thing. They lose their 40,000$ car and its status when they have to follow a humble bicycle. You are not another American on a vehicle to some of them; you are a peon between them and their royal lazy boy throne. Vehicular homicide is funny to some people, like throwing rocks at birds. The only people that value the life of a motorcyclist is another 2wheeler rider.
