The point of massive fines, and in some cases jailtime for driving without a license is control.

If someone breaks regs, you want to be able to levy fines or jail. If they do it a lot, you want an inability to drive at all.

It's about regulating poor drivers. And yes, initially vetting a driver too.

I don't really know any adults who don't drive, and nobody ever told me they weren't capable.

I don't think it's about driving ability, besides the initial vetting.

Most inadequate drivers don't think they're inadequate, which is part of the problem. Unless your acquaintances are exclusively PMC you most likely know several adults who've lost their licenses because they are not adequately safe drivers, and if your acquaintances are exclusively PMC you most likely know several adults who are not adequately safe drivers and should've lost their licenses but knew the legal tricks to avoid it.

From the perspective of those writing the regs, speeding, running lights, driving carelessly or dangerously (all fines or crimes here) are indeed indicators of safe driving or not.

Understand, I am not advocating this. I said I did not like it. Neirher of those statements have anything totk do with whether I think it will come to pass, or not.

I am ~30 years old and I do not drive. In fact, I cannot drive.
