Abstract
Experienced road users seem to have their own set of traffic rules (including rules about when to violate the official rules). The number of violations is enormous, causing great concern for the authorities. The situation could be improved by separating a set of rules with the aim of deterring road users from dangerous behaviour and a set of rules instructing correct behaviour. The first set should be small and formulated to satisfy the lawyers. The second set should cover almost any situation for any road user with a presentation aimed at these road users. An opponent remark is presented by G.Kroj.
