Does the rule say you can't cross the line? Seriously, I don't know. He clearly DID cross it, but whether he gained a "competitive advantage" by doing so is a matter of opinion.

But what kind of crap is it to fine the winning car's team or owner, or chief mechanic or whoever when the car fails inspection at the end of the race? They should either make the inspection less stringent, or disqualify a car that fails inspection. JMHO.

If you didn't watch the Brazilian Grand Prix on Sunday morning, you missed a good race there, too.
