I can't imagine that's how cognition and an activity like driving interact. It's not like negative reinforcement in a social setting (getting demoted at work and as a result getting discouraged and becoming a worse performer, for example) - most people realize driving is an inherently dangerous activity, and most people don't want to die (even if they're doing moderately risky things like driving stoned), so they're not going to have an emotional reaction like "Welp! Guess I'm just fated to drive like shit since I'm stoned right now, hope I make it home, but first lets do some donuts." No, they're going to overcompensate and drive more safely. If anything, I'd be concerned the opposite effect would occur - data suggesting that driving stoned is safe will cause stoned drivers to lower their guard and not compensate for their impairment as much, and thus raise stoned driving accident rates.
