The point about people standing out doesn’t make much sense when you consider the following. If a service member brings over their Dodge Challenger, a car that is not common in Germany due to its ridiculous fuel consumption, they too will also stand out. What about a Ford Mustang GT? Or maybe a dual cab F150 in any of the millions of trims available?
Germany is quite content with some ridiculous vehicles and invented most of them.
What stands out is say civvies driving on military number plates (UK until the 80s). In this case, anyone driving a banned vehicle - these beasts have sharp edges and are banned.
No one has a problem with a Ford Musty GT - its just a car and not sharp.
Safety? Yes, agree.
