An enhancement of the speed limit for cars on the dutch motorways from 100 km per hour to 120 km per hour will cause both higher speeds and greater differences in speed. This will result not only in more accidents but also in accidents of greater severity. It is also not likely that better police enforcement would decrease the differences in speed and improve the traffic safety as such. It is suggested that the police could detect drivers who were speeding under the most dangerous circumstances, say at more than 130 km per hour. The risk of arrest for those drivers would be so great that their numbers would be greatly reduced. The limit for police detection could then be lowered say to 125 km per hour and the process could be repeated. With smaller speed differentials a decrease in accidents with severe injuries can be expected. For the original article see http://www.verkeerskunde.nl/Uploads/2013/12/artikel-F.Wegman-VK-april-1…
