I have grown to believe in the value of the "an ounce of prevention is worth a pound of cure" school of thought. Whether it's regarding driving, riding, gun ownership, health, reproduction, drug use, et al the result always seems to be more effective, efficient, and longer lasting if it's covered on the front end vs the back end via punishment. Based on the studies and programs I've seen, every one of the items listed above has seen massive improvements if funds are directed education, training, and ongoing support efforts instead of punishment via police/law enforcement.
Look at (Northern) Europe or Japan; longer, more rigorous training (and better maintained roads) helps to keep them among the safest drivers in the world. In the US, most people get licensed without any clue how to properly pilot the majority of daily situations; further, they barely get any training on etiquette (things not necessarily addressed by law but are part of the common understanding, eg relative traffic speed should decrease among each lane right of lane 1; the left lane shouldn't be the "park my ass here until I exit" lane")
The other areas I mentioned are less relevant to the thread, but follow the same idea; access is too easy, missteps aren't corrected, retrained, or supported... only punished.
I wish the US put more emphasis on preparation for the freedoms we have. Our social contract REQUIRES that people not only have their various freedoms, but (more importantly) know how to responsibly exercise them. Circling back to topic, I really would like to see more pushes from organizations like AMA to totally re-tool licensing requirements. THAT is the failure I'm most frustrated with. I have multiple friends that just recently passed MSF/CMSP but didn't get basic (or thorough enough) training to comfortably and confidently hit the roads at large. They were scared to get on the freeway because they'd never gotten training on one or at that speed. They didn't know why certain lights weren't triggering for them or about the concept of "dead red" (though CA doesn't have an actual exception for, but 2-3 cycles is etiquette AFAIK). They didn't know to back into parking spots instead of nosing in. They didn't understand what are the pros/cons of leaning or counter leaning in certain situations. They didn't know the proper etiquette for splitting/filtering. And on and on... I'm not knocking the trainers/programs - they did the job they were tasked with doing and some of these ignorances weren't uncovered, simply under-instilled.
