Pretty much everywhere that has a vision zero program related to traffic incidents does it primarily through road engineering and developing alternate modes like public transit and bikeped.

Enforcement is only valuable when it’s fully passive and catches everyone - speed and red light cameras, license plate scanners for congestion charges, etc… This is true of any kind of enforcement response to try and reduce rates of bad behavior. Catching offenders doesn’t work as a deterrent unless most offenders think they will be caught.

And the bad drivers, the ones who people say shouldn’t have licenses because they’re not competent enough to control their vehicles… They probably wouldn’t be driving if they didn’t live in a society that required and encouraged they do so. In a normal, healthy culture, people usually don’t substantially prefer one mode over another. They just want whichever one effectively and affordably gets them to their destinations. With the average annual cost of car ownership over $11,000 in the US, it really isn’t very affordable already. But it’s the only effective way for most people to get around.
