they were obviously driving an 18 wheeler simulation and besides that it didn't look like an accurate simulation of that. I think the undercover video of the station's camera men said it all on how dumb it would be to base any study on that. I've driven for over 10 years, have no accidents either high or sober. And I smoke n ride all the time it's a favorite pastime of mine. Now I try my hardest not to drive drunk and rarely do but let's not compare to two.
