<< good luck stopping with a 2 second gap doing 70 mph behind someone jamming the brakes >>
ding, ding, ding--we have a winner!!!!
you are 100% right. guess that explaines how so many 10-car pileups happen
people, people, people.....do you not understand, that as your speed increases, the distance that you travel in two seconds greatly increases? So the two second rule applies at any speed. If you are driving 70 mph, you might have 100 yards between you and the car in front of you, and going 30 mph, it might be 40 yards. Get it? (The yardage was not calculated exactly, obviously). So as long as you stay two seconds away from the person in front of you, you should be just fine. The problem is, no one does that.
I try not to tailgate people, but I usually end up following at 1 second, but I try. People that drive in the left lane with right lanes open anger me. Greatly. If I am on a one lane road, I do keep my 2 seconds or more, because I know I cannot pass them, or I do not intend to. If you drive more than 10 under on small, low speeds roads, you WILL be passed by me, if at all possible.
Now, to the tailgating thing......people assume that noone will ever slam on their breaks in front of them because it has not happened to them before. Its the good ol' Pavlov(sp?) conditioning. You are taught from experience that nothing happens when you tailgate.....untill one day, someone slams on their breaks when you were not expecting it, and you rear end them. Now that you realized that people do slam on their breaks, the majority of people probably will not tailgate for a while, some never again. Eventually, the people will go back to tailgating, because they have gotten used to people not slaming on their breaks.
did that make sense?
oh, and I was driving back from dallas to austin down I-35, and there were a couple of occasions where there were easily 100 cars all tailgating each other unusually closely. I kept my distance, because if one car in front slams on his breaks, the whole line is going to slam theirs on. It was a pileup waiting to happen. If the cars would have been unable to run off the road to avoid rear ending someone, a 100 car pile-up could have easily happened.
