I spent a couple years as a driving instructor and licensing examiner. It is disturbing how hamstrung I was on failing people. And that many people openly talked about losing good habits/forgetting important info now that they don’t have to test any more is an extra layer of terrifying. Mandatory retesting every 3-5 years, more if someone has a lot of infraction/collisions, and yearly after 65.
Large mobs and guillotines seemed to work fine a while back. Larger mobs and guillotines should still do nicely.
