It says in the article that people who lose their drivers license on account of speeding usually keep on driving anyway. I also feel like this is already the case in a lot of countries yet speeding still exists so I don't know if I agree that this is this simple solution no one is thinking of.
That feels like it could be fixed with forced impoundment or surrender of the offender's vehicles, and a certified mail notification to everyone they might know that might loan them a car notifiying them that if they do lend their car to the offender knowingly, they'll be held partly liable.
It's never going to be perfect, nothing will, but reducing the odds of bad behavior reduces the odds of bad outcomes.
Most police cars that I know of have license scanners and that scanner will inform police if the owner of said car has a suspended license, which results in an immediate trip to jail.
