Well, the question is : why are they the worst ?

At least a driver with a license have been officially trained with security in mind.

Those EPA drivers are, actually, teenagers trained by their teenagers friends. It’s normal for teenagers to underestimate risks and dangers.

That’s basically why a licence is needed to drive : not to explain you how to control a car (that’s a rather simple skill) but how to act on the shared road.

Do they not have a license because they'd rather self-learn, or do they not have a license because they don't meet the required age?

While I don't doubt that some people would not give a shit and self-learn and drive the A-tractors without a license anyway, at least lowering the age for a license would mean that those who want to be safer can get it.

You could even attach restrictions to said license that incentivise safer driving over time - a teenage license can be obtained at 15 but comes with some restrictions that get lifted over time (unless caught breaking the rules) and inherently "converts" to a full license by the time you're 18 assuming you haven't lost it beforehand due to unsafe driving.

The real reason you need a license to drive is so that it can be revoked if you act like an idiot.
