Some room for improvement here but many people will ignore training regardless of how in-depth it may be. So I think the bigger issue is the infrastructure that allows and encourages unsafe behavior.

If it’s going to work you’ll need meaningful levels of enforcement and punishments for unsafe behavior, including license suspension. Suspensions are rarely used today because it’s seen as “too harsh” for most infractions. The lack of alternatives to car based transit makes it an economic death sentence. So again, the solution will need changes to and investment in infrastructure.

But the problem is bad so I’m certainly open to these educational approaches in combination with other changes. What I’m not open to is the common attitude of “It’s those other bad drivers’ fault so I personally don’t need to change anything.” Until this gets better I think all road users have a moral obligation to advocate for change.
