Put it this way - trucks try to leave enough of a safe distance between themselves and the vehicle ahead. In this case, with 86,000lbs on the trailer, he would need to leave 1 football field (100 yards) between them....
I know what you mean! I drive 100 miles a day to get to work/home. There are 8 miles of construction with reduced speed. I TRY to leave the suggested space between the car in front of mine. Does it work??? HECK no, why? Because of the idiots who drive 70 in a 45, the idiots who don't notice that all lanes have just stopped, etc etc. People who are more IMPORTANT than anyone else in the world, or should I say selfish?
I think most problems would be fixed by using the Golden Rule!
I do feel for anyone, car drivers, truckers who have to drive for a living. They get to see the morons of the world.
