Earlier quoted context omitted.
There was a time when people were allowed to drive cars unlicensed. These days, that seems insane. As the traffic grew, as speeds increased, licensing became necessary. I think, these days, we're almost into that category. I don't say this happily. But having unrestricted access seems like an era coming to an end. I realise this seems unworkable. But so was the idea of a driver's license. Sometimes society and safety…
If I threw my license away tomorrow, what would be insane about me driving without a license? Are you saying "unlicensed" where you mean "untrained?"
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.
