Their page also has some interesting statistics about driving in Slovenia, like the fact that traffic accidents have nearly quadrupled since 1960, but that the number of deaths is on the decline. “Only” 274 people died two years ago, which is also very low when taken as a percentage of the population. But the number of injuries continues to rise.
For more European statistics, you can also try the Project on Social Attitudes to Road Traffic Risk, which is full of interesting stuff. For example:
* Irish and Dutch drivers are most likely to approve of regulations on alcohol and speed, the Danish, Swiss and Hungarian less so. (source)
* A solid majority of drivers in the EU “always” wear their seat belts, except in Italy and Greece.
* The majority of Italians nevertheless believe that they drive “more safely” than the majority of Italians. (source)
* Among Europeans, Poles are most likely to enjoy “driving fast.” (source)
* Cypriots are the most likely to chat on the phone in the car. (source)
* Finns are most likely to be stopped and tested for drunk driving. (source)
* Nearly half of all Dutch drivers have gotten a speeding ticket in the past three years. (source)
