I think several of us have told driver's license stories in other threads, but since someone asked and the thread is already so, er, discursive ...
Many decades ago, we were either required or recommended to take one semester of driver's ed in (public) high school, balanced by another semester called "health" that included a very modest amount of sex ed. Both were extremely dull, but we were at least exposed to basic traffic laws, statistics like braking distances and times, and I believe even one driving simulator, which in those days was an amazing new high-tech device.
Only at the very end of the semester did we each get a very few in-car practice driving sessions, in a car with dual controls and the coach, er, driver's ed teacher, in the front passenger seat. I don't remember that being helpful for much, only being nagged at to stop far enough behind the car in front so that we could see the place where its tires touched the pavement (defensive driving was a relatively new thing), and being nagged at for going even a mile or two over the speed limit on an empty side street with zero traffic.
By that time, I believe I had already taken the written test and gotten a learner's permit, so I had already started driving with my mom or dad in the passenger seat, which was legal from age 15. The only hard part of the road test was parallel parking, which we pretty much had to learn on our own with our parents to get enough practice. But we could practice at the DPS office after hours, using exactly the same spacious-sized parking place that was used in the actual test, which only meant memorizing visual landmarks like poles and cones in order to turn the wheel at just the right moment. We had to get within a certain distance of the curb -- maybe 6 inches -- without ever touching the curb, which would have been an immediate disqualification. That pickiness seemed harsh at the time, but in fact, unlike earlier generations, we never had to learn things like driving a manual transmission at all, which I have since occasionally regretted, but not a lot. (Now I believe kids don't even have to parallel-park, the wimps.)
I still appreciate the defensive-driving elements of that basic instruction, and have always tried to be careful about wearing my seatbelt, not changing lanes into someone else's blind spot, keeping a safe distance behind the vehicle in front, etc. However, because gas is kept artificially cheap by the petroleum lobby, and because many more people now commute to work in cities, and because of NAFTA in our region which brought considerably more truck traffic on the interstates, there are now simply a lot more vehicles on the road, along with less funding to maintain streets and roads.
And in some places there are also more bikes, which none of us were ever trained to deal with, because in our day, bikes were only what kids rode around the neighborhood. I do find the places in larger cities where I now have to watch for bikes crossing quite disconcerting, as the bike lanes have usually been squeezed in decades after the roads were designed for cars, so they require a lot of extra paint and signage that can be confusing to decipher in a hurry for people who don't actually live downtown. And they may contain young bikers going at what for me are speeds much too fast for a mixed environment where bikes and cars are competing for the same asphalt, so sometimes even after I look one way, and look the other way, by the time I nose out and try to cross, there's already some biker zooming into view who was nowhere to be seen even a second earlier, possibly already gesticulating at me as if his speed is my fault.
Surely in the longer term, dedicated bike lanes separated from streets would make everyone happier and safer. But given the budget and space constraints of large cities, and the fact that bikes are always going to be a lower priority than police, fire, hospitals, schools, etc., I don't see that coming in the US any time soon, unless there is ever another fuel crisis, or a carbon tax, that provides a much stronger incentive not to commute by car. Against that, though, are our suburban sprawl and low population density, which make public transportation of any kind an uphill, underfunded battle in most cities outside the urban northeast corridor, and practically nonexistent in smaller cities and towns. I feel I do what I can by not taking unnecessary trips and not owning a hulking SUV or massive extended pickup, even though those heavy vehicles are exactly what the current petroleum-friendly administration is actively promoting and thus what the car industry is once again wastefully churning out.
But as many of our friends are now in the oldest generation, I must also say that a car whose seats are a little higher off the ground than a traditional sedan is considerably easier for elderly people to get in and out of. I might actually consider something like a minivan now, where none of us would have before. Ride-sharing and ride-hailing may eventually be an option when my generation is elderly, but for now, it's almost impossible for older people to give up driving without also moving into some kind of care center that has a shuttle service available, or indeed, all meals and health care on site.
