In much of Europe there's no need to own a car at all. Towns have grown up around railway stations, and shops are close enough to walk/cycle.
The problem in the US seems to be that homes/workplaces have been built up around roads instead of rail infrastructure.
More importantly - since this discussion is about driver behavior - if you look at traffic deaths per vehicle, per driven kilometer, or even per inhabitant, the US do better than a lot of European countries. [2] I'm sure that the total disregard for the existing bans on cellphones [3] for drivers is a factor here.
Also, regrettably, Europeans are repeating the mistake that I hear some US cities are now regretting: building giant shopping areas outside the city centers, thereby destroying commerce in those centers and worsening the traffic situation. In one particularly megalomaniac example [4] they want to build a giant shopping center right next to one of the busiest roads in Belgium (the ring around Brussels), less than 10km away from several existing and perfectly fine city centers.

Nanny states are borne from thought processes like this.
It doesn't matter that the overwhelming majority of drivers don't get into accidents because of their phones, nor does it matter that eliminating risk from an inherently risky activity such as traveling in a 3000-pound metal object is all but impossible.
Regulations and rules are useful. Banning things outright is ridiculous.

The solution? Self driving cars. I'm convinced that every dime we spend on any transportation-related activity besides the self-driving car is a waste of time. Every year, about 30,000 people die from fatal crashes:

That's twice the number of people who die of AIDS in any given year:

Electronics aren't the enemy. Drivers are.
