So I gave it a few days to settle in and calm down from my absolute outrage.  That said, I can't believe the move Kevin Harvick made on Riggs with just a few laps to go at TMS. 
For anyone who missed the race, Harvick put his nose right up against the rear of Riggs' car, which effectively takes the air right off the back end of the car.  He didn't make contact with Riggs, but I'm sure most will agree, it's awefully hard to recover a car when the rear wheels aren't gripping.  I'd think that's especially true coming out of a turn.  I also think it's a particularly dangerous move.  I'm having a hard time differentiating this from intentionally wrecking a guy.  At the same time, I think Riggs' tire carrier acted out of frustration, however inappropriate it was.  I do not condone that, or any other kind of retaliation in sports.

Harvick wasn't exactly in contention to win the race.  At the time, he was in 4th place, and he was going to finish in the top 5, second amongst chasers.  He had little to no chance of catching Johnson, let alone Stewart.  Even if he had caught them, I don't think he had the car to beat them.  So what's the point of dropping your nose so close to a guy that he crashes? 

I'm not exactly a NASCAR know-it-all, and I try not to pretend to be.  But this just seems reckless and dangerous.  Deep down in my gut, I almost want to scream that he wrecked Riggs just to have a chance to get to the leaders, and should be docked points the same as Robby Gordon at Atlanta.   

I guess I'll stop ranting now, but I sure would appreciate it if someone'd help me understand why NASCAR tolerates this kind of thing.
