Teen drivers are not great drivers. They’re more than likely going to wreck, and when they do, you want them having modern safety features like crumple zones, active seat belts, airbags, etc around them.
You also want to give them the tools to avoid an accident if possible, ABS brakes, blind spot monitoring, etc.
Idiot teens are, as the name implies, idiots. They’re more likely to crash, so they’re more likely to need all the crash protection you get in modern cars. You can make the argument that active crash prevention features, like blind spot monitoring and automatic emergency braking, teach bad habits — but you can also make the argument that they mean more alive kids.
