Please blink before every turn!

When I’m on Swiss roads at the moment, one thing strikes me again and again negatively: the automobileists increasingly push the timely set of the turn signal – or they “forget” it completely – before they initiate a braking process with the aim of finally turning off. This immorality makes it impossible for the forward looking vehicle driver (I) to drive an economic (and ecological) way. Here again the old-known rule for all who do not know (want to) ): 1. Foot of the gas 2. Watch and turn signal 3. Insignia 4. If necessary brake (but only now! ) 5. Turn off Do you know the problem?
