I get tempted to do it from time to time. If you can catch a truck doing over 70 they have an enormous effect. If I let myself get within 20 feet on him I can coast and literally have had to hit the brakes to stay that far back. And all this in a 7500 lb pickup.

That said, my old ticker cannot stand the prolonged stress of tailgating semis for any meaningful length of time. I have driven too much and seen the debris that trucks can kick back at you.
