The “another” law in question

Graduated driving licences could see a minimum supervised learning period, curfews and a limit to the number of passengers new drivers can carry.

Of course reckless drivers who were going to drive drunk won’t respect these either, but also these are laws that can dissuade parents from giving/lending their cars. Surprisingly a bunch of parents are oblivious to their kids drinking and driving patterns, but a blanket ruling like this might help.
