Let’s say there’s a truck in the right lane going slower than other peoples’ liking. There’s a line of 10 cars in the left lane that wants to go round it, and more coming up from the back. Not one of those people in the left lane will move over to the right lane to let the faster car behind them go past, using the ‘wait your turn’ philosophy. And the lead car can see 10 cars behind it, but isn’t going to speed up because ‘I’m going fast enough, they can wait.” And then someone comes up in the right lane, the cars in the left lane will disregard the common sense of keeping a safe distance from the car in front of them, and all of them will bunch up to prevent the person in the right lane from getting ahead of them, putting all of them in danger of a chain reaction accident, all while traveling at about 100’ per second at 70mph.
That’s the American way!
