>Other than the data of road fatalities that disproves this anecdote,

You can't make that assertion (well you can, it's called "lying with statistics" but that's beside the point) without knowing if the fatalities the result of the accident rate or just a higher conversion ratio as a result of reduced safety equipment, reduced seatbelt usage, more motorcycles, etc, etc, worse emergency services, etc, etc.

INB4 other people start whining on your behalf, I'm not saying those countries aren't less safe to drive, just that you can't do a straight comparison of accident rates and fatalities without considering the conversion ratio.

Of course you have to consider confounders. That’s why transportation data usually includes best efforts.

But at some point you have to look at the totality of the evidence. Countries with better road infrastructure, enforcement, vehicle standards, and driving behavior generally produce better safety outcomes. The fact that multiple factors contribute doesn’t make the observed outcome meaningless.

As I already stated there is absolutely systems that increase the perceived sense of risk that can help outcomes (road width sizing, roundabouts, minimal signs/lines) but those typically work best in a system where there is already some sense of order.

Less Reddit style snark would go a long way too.
