When I taught my kids to drive I tested them on the potential risks, traffic, and the location of the cars in back of them as a running narrative. I taught them to be active drivers, always scanning, noticing, evaluating, anticipating trouble. Downside, they all started "talking" to all the other vehicles while dirving, like "What the hell are you doing..., are you serious?", etc. Knock on wood, 3 kids with 20 years combined driving experience, no accidents. Let's hope we all stay attentive. Note: When my son passes a cyclist I suspect he'd notice what gear the bike's in.
