NASCAR sowed the seeds for this kind of behavior. And here's what they end up with: a hot-head ramming another driver while UNDER CAUTION, fer crissakes, and taking him out of contention for the championship.

NASCAR knows that it's boring just watching cars go around in an oval. NASCAR knows it's boring seeing one car dominate a race. So its rules have favored bunching up cars and tolerating - no, encouraging - contact between cars.

It's ridiculous, and Kyle Busch's actions are the logical result.
