The better the car infrastructure, the better quality (in terms of modernity, maintenance etc) of an average car on the road, overall the "easier" it is to drive, the worse the drivers in that society are. This should be pretty obvious. I've lived in two countries in Europe, one with a much better/more sane car infrastructure and in that one no one knows how to drive. Which means when something unexpected happens on the road they're not skilled enough to handle it. In the other country I had very stressful/complicated situations almost daily, such that the rules didn't tell you how to act and it was the wild west sometimes. That's when you really learn how to drive, when you're pushed out of your comfort zone by other drivers or by the circumstance on the regular. Not when you drive automatic in perfect weather on wide roads drinking your large coffee with your right hand.

Another factor is that not everyone is supposed to drive, eyesight or other health (also mental) issues prevent some people from driving, but in the US everyone has to drive to live so those people drive as well even if they know that they shouldn't.

In my 2-3 weeks trip in the USA I saw a glimpse of this, very car centric culture but the culture is only about the machines not about the actual driving. People there only know how to drive in ideal conditions, in their wide lanes, gigantic parking lots etc.
