Tracy is beginning to realize he's on the down side of his career now, and when he can't beat someone fair and square on the track he resorts to kamikaze tactics.
He doesn't have much else left to rely on these days. AJ makes him look like a chump every week, and he hates Seb because Seb is the guy that first kicked Tracy to the curb.
Seb may have reached his plateau in Champ Car, but Tracy has clearly been knocked off the summit and is on his way out.
Oh well, there's always the NASCAR Truck Series for him.....
