Interesting read.
My wife rides me constantly about my tendencies toward "road rage" (which I don't deny), and this article illustrates what I've said for years: it's the SLOW drivers, not the fast ones, that create carnage on our highways, because they force frustrated drivers to take unnecessary chances.
Has anyone also noticed the frequency with which slow-pokes (on two lane highways) seem to find the gas pedal once you try to pass them?
We used to call it "tracking". Drivers who do not see well or have poor driving skills will instinctively use another vehicle as a speed gauge. That is why they speed up when you pass them and then slow down once you have gotten past them. They will then drive at a slower speed until another person comes along. I pass these people at the highest possible rate of speed and then cut in front of them to avoid accidents.
