1. Force people seeking a driver's license to undergo classes, regardless of their prior self-education. In my opinion, a significant amount of irresponsible and incompetent driving stems from the early failures in parents teaching their kids properly. People not only don't learn everything they need to, but they don't respect driving as the dangerous activity it is.
If someone succeeds in obtaining their license, they must then re-test every five years to maintain it, regardless of their age and driving history.
2. Augment the new mandatory classes with virtual reality lessons. The VR headsets will ostensibly drill driving skills before they're practiced in a real vehicle.
But the real reason they'll be used is to force candidates to experience high fidelity simulations of hitting and killing people while in the vehicle. They will be exposed to the immediate trauma involved in hitting a family in a sedan, or killing a pedestrian who was adhering to the rules of the road. It might also be helpful to force them to watch footage of people being seriously injured and killed in vehicular collisions.
This recommendation comes from two hypotheses of mine. As the article states, people overwhelmingly know distracted driving is dangerous, but they can't help themselves. I believe this is because 1) they have no way to activate empathy for the potential danger they present to others, and 2) they do not take driving seriously enough. It is treated as an innate right with loose rules, not a dangerous activity sustained only out of necessity to keep urban society functioning.
Unfortunately, this proposal will never happen. I know parts of it are extreme, but I don't see an alternative for fixing such a systemic problem which isn't extreme.
