About a dozen years ago I was riding back home from the doctors and a red F350 was used to intimidate me. The rear wheels approached me thrice. Then the vermin dashed ahead cut across the other three lanes of traffic and entered the left turn lane. I was able to also make the left and saw the Ford enter a parking lot. I managed to lean my Tandem on a light pole and approach the drivers side window where he had parked before he exited the vehicle. I got the drivers attention and immediately made it clear I wanted words not a fight. He told me that he had ended up behind some riders and couldn't go faster than around 8 mph for some distance. They had refused to let him by when they had room to pull over. So 15-20 some odd miles later he sees the slow moving fat man on a Tandem and takes his wrath out on me. OK he was a little more humble than that. his wife was sitting next to him the whole time and neither one of us used profanity while we conversed.
