How about these dangerous and annoying behaviors:
Tailgating!
How could Tom & Ray have left this one off their list?
If someone is…let’s say…the last car in a line of slow-moving traffic, why do some drivers see fit to tailgate the last car in line? The driver being tailgated cannot go any faster than the cars in front of him, and no matter how much the tailgating jerk in back of him might want to go faster, the person in front of the tailgater is also unable to go any faster than the cars in front of him. This situation is not unusual on roads that have only one lane in each direction, complete with “no-passing” zones.
All that this dangerous and inconsiderate tailgater accomplishes is to make an accident more likely if the driver in front of him/her needs to suddenly slow down. Incidentally, over the last few years, I have observed that the majority of tailgaters are women in their 20s and 30s, who are likely to also be yakking on a cellphone while tailgating, thus making them less likely to be able to react quickly in the event of a sudden slowdown of traffic!
The “creep”!
Someone is attempting to enter a fast-moving roadway from a side street, or a parking lot, and instead of keeping his/her car completely stopped until a safe opening presents itself, he/she slowly creeps out–inch by inch–until it is necessary for cars traveling at perhaps 40 or 50 mph to swerve out of the right-hand lane in order to clear the offending “creep”. It is not reasonable to expect cars moving at 40 mph or more to stop for someone entering the roadway from a side street or a parking lot, and to have to swerve can cause cars from the right-hand lane to collide with cars in the left lane.
