Obligatory US, I think the better way of filtering bad drivers is more stringent and frequent testing through the DMV (or your state’s equivalent). Look at Germany, they don’t mess around when it comes to licensing. I’m mid 30s, and haven’t had to retest or do any form of continuing driver’s education or retesting since I was 16.
It’s a little trickier here in the US due to our cities being built for cars, and being without one can be a huge detriment, especially with most public transit being a shitshow. But I agree, we definitely need some mechanisms to weed out bad drivers.
While licensing is definitely harder in Germany you also do not have to retest or do anything else to keep your license. It’s actually a problem that it’s pretty hard to take away the license from old unfit people (and the German government actually blocked EU legislation improving that).
