The way i see it, if the situations are right there's no real harm to racing someone unless it's EXCESSIVE like the guy in the truck was trying to do. You just happened to hand his dignity back to him in the form of smoke from your tailpipes. I have rules about when i decide to run someone:
only once, twice if conditions are perfect
straight road only with a clear line of vision, because you never know what's ahead
i only go up to 100mph because by then it should be pretty clear who won
You did this guy a favor because maybe now he'll realize that instead of being an @sshole with a fast truck, he's just an @sshole. Good kill, sometimes there are just times where a race is "appropriate" - but of course i'm biased.
