Teen driving safety is an important issue because without it, a whole lot more people would be dead before they even reach adulthood, and that alone is a problem for society as a whole. Driver's education, although it plays a huge role in keeping them as responsible drivers, there's only so much it can do.
I’ll be real, most teens aren’t going to listen unless they either get first hand experience, or it’s another teen they KNOW telling them (or someone they trust in general). In this day and age, even if you try to warn them, some just won’t listen because “why should they?” They don’t think they’ll be in a situation where they’re going to get in a crash or it could well be because they think they know better. That in itself is the largest hurdle, but there's also variables like “can anyone else in their family teach them on top of drivers ed?” or in other words, “do they have a way to gain more experience in a safe environment?”
Of course, there are ways to overcome these challenges such as being open to learning as a teen and not thinking you know it all, because they don’t. But gaining more experience in a safe environment is conditional because not every student has parents or guardians, or anyone to look to for help. So the best way to ensure they get all they need from drivers ed would likely be to either extend the course so certain students have a better access to such a tool, or offer free opportunities to drive in a safe place and learn the rules of the road.
Even go-karting (although it would likely need to be toned down if it’s to teach driving safety) is a great way to help them learn more driving ability while being in a safe environment. There are so many ways to help student drivers drive safely, and though some may be costly, some are truly not that hard to implement. It’s just a matter of are we willing to put in the time to implement them?

Speaking from my own personal experience, although I didn’t get to drive on a road or highway before taking drivers ed, I thankfully had plenty of opportunities to learn about driving and how to do it safely. Of course, as I said before, it’s a matter of having a safe environment (like a school parking lot, or even from the passenger seat trying to keep the wheel straight in my experience) to be able to learn. Even games are a way to help teens learn how to drive while still being fun or engaging.
Then on top of all that, I am very thankful for my drivers ed experience because without it, I don’t think I’d be writing this right now. Some time in 2023 I believe, around when I was more comfortable driving, I was driving in California (Las Vegas) pretty early in the morning with my family in the car when a car in another lane swerved off the road into the woods. I have never been more thankful that I keep my distance from other people while I’m driving, because if I didn’t, I’d be in the woods crashed against the tree and dead.
You have to be so SO careful when it comes to driving because just because you drive safely, DOESN’T MEAN EVERYONE ELSE DOES TOO. But your chances of still being out of crashes and unharmed on the road are far higher when you STAY SAFE and don’t drive recklessly too.

To reinforce staying safe while driving, but still take some action is to hold events specifically FOR teens that gives them a chance to drive, but keeps them in a safe environment. Things like go karting (as I mentioned earlier) would be very fun for teens to learn better car control incase of emergency situations, but also learning that some may be more reckless when driving than some others are. It can even build driving confidence so they can stay calm when on the road instead of panicking.
And again, like I said before, you can even give out occasional free driving lessons for people of a certain age so they can learn to drive safely and gain more comfortability doing so. You could even add in a scoring system and give the best safe driver a prize for their driving. (If you phrase it as safest, they just won’t drive at all, or go 2 miles an hour because “it’s safest.” Trust me, I know. I may be 19 but that’s something I would certainly do out of spite.)

So simply, just give more chances to drive in a safe environment.
