Hi! Around the turn of the year, the “W” registration marks are introduced here in D. So up to 3 cars drive over 1 registration plate and only pay the taxes + insurance for the most expensive. As far as the theory is concerned. Now my thoughts about the practice: I drive for example at my PickUp the small (in the meantime only hard to get) registration plate. Suppose I would eventually buy a city intelligent car (to make the cliché perfect: 3L Lupo). As far as the “normal” markings (normal dimensions) are concerned, there are already good products (especially on the Swiss market) that make it possible to change the markings by means of a click mechanism without screws in seconds. Now I wonder, what does someone like me do, who wants to quickly pack the small rather square-looking markings from the PickUp to a Lupo to go shopping? Do you have any ideas? There are not yet any solutions for this. Just like the thing about the TÜV plaque?! It is then determined (similar to Switzerland) to glue the windscreen from the inside, instead of on the license plate. Greetings, Lukas.
