I mean, you can see how a kastenwagen nutzfahrzeug is a very different vehicle from a consumer mid-size pickup, right?
Sure, technically some would call the vehicle you linked a pickup, and technically German law still identifies the consumer pickup truck as a nutzfahrzeug instead of a PKW, but it doesn’t feel like you’re making a best effort to meet GP in the middle.
The distinction gets at something interesting though, and it's a weird intermingling of culture and politics. I think a truck as owned by a consumer, and as an American would understand the word, is, at least in part, a lifestyle statement derived from maybe overprovisioning on the horsepower. Such a lifestyle statement in Germany seems to be perfectly socially acceptable when it ties in with luxury and doing your "civic duty" by buying German, but it clearly ruffles feathers and meets with political headwind when it ties in with the culture and financial constraint of the "commoner".
