First off, I want to state that I agree heavily with this.

I teach driver's education and want to add that what has helped my driving the most has been the mere repetition of truisms ("don't drink and drive", "look where you're going while backing up", "think about what you're doing", "check you're blind spot before moving over", etc.) and the knowledge that a crash resulting from these types of failures would be especially low status for me. When I'm tempted to keep driving late at night vs. pulling over at the next exit for a rest, the thought of my friends, coworkers, and students judging me harshly were I to crash gets me to pull over when all else fails.

One note:

Solution: Watch this 30 second video for a vivid comparison of head-on crashes at 60 km/hr (37 mph) and 100 km/hr (60 mph). Imagine yourself in the car. Imagine your tearful friends and family. (emphasis added)

That video is great, and helps get the difference on a gut level. But vividly imagining one's friends and family morning their loss can increase suicide rates in those that are already predisposed.
