>>Tailgating is aggressive behavior.<<
Yes, and like all aggressive behavior, it has its place. Even on the road. I’m a huge fan of Louie L’Amour novels about the old west. He writes them from the perspective of historical accuracy. Real men really do get aggressive when it is called for. They are willing to risk pissing off another man when the other man is infringing on his territory. Those are the “mens men” and the ones that get the girl. And this is actually true in real life today.
One place it is most definitely called for is on freeways with road hogs in the passing lane. I’m not talking about the guy that is passing another car, even relatively slowly, but the real road blockers, whether they are doing it intentionally or they are oblivious. And if flashing your lights at them doesn’t do the job, it is time to up the stakes. Is it risky? You bet. Life is risk.
