He make mo' money mon if he drive da white man slow....
Seriously, I can't imagine why they say getting high would impair his judgement on getting out and on to the track. I have seen many drivers including Tony Stewart and others do the same thing in the cup series. They wait on the track until the driver they are pissed at comes by and they toss their gloves or helmets at the moving car. Sometimes folks even wreck others on pit road. I was at a race when Tony Stewart did that because he was pissed.
Kevin Ward was driving in a race and he wasn't going so slow that he was getting lapped on a constant basis was he?? I haven't watched the clip in a while. Pot will do many things like making people laugh, eat, sleep and be content with things but raging like a madman? Nah I don't buy it. Maybe the guy smoked pot that morning (still doubt it) the night before (still don't buy it) but I cannot believe that had anything to do with him being pissed and wanting some justice.
Hell look at the road rage on our roads! Bad judgement is easy and common even without smoking weed.
