Just Friday coming home from work, I witnessed someone angrily trying to get into a vehicle war with a loaded cement truck. This guy in a Bronco kept swooping in front of the truck and hitting his brakes, forcing the cement truck to slam on HIS breaks, then the Bronco would swing to the side and get next to the truck and swerve over like he was going to hit the truck - apparently trying to force the cement truck to flinch over and get forced off the freeway. I couldn't believe my eyes. I kind of hoped the cement truck would just hit him. Everyone on the freeway had to slow way down to avoid this crazy guy, there are only 3 lanes and he was all over all of them. He finally dove off on an exit at the last possible second, almost clipping the front end of a wheelchair express bus. He must have been high on something, that was NOT rational behavior!
