And even if you are a farmer, an american pick-up seems to be a rare choice around here. If you see something pick-up-like, it's usually more a variant of UniMog https://en.wikipedia.org/wiki/Unimog .
And for the "small-time farmer without enough money to buy lots of equipment" (rare nowadays), tractors with tons of included functions were often more practical: https://de.wikipedia.org/wiki/Fendt_GT (no english version, sorry). Since Germany is more dense and distances are smaller, low speed is less of an issue I guess, compared to the US. And you can pull real farm equipment, which a pick-up car usually cannot.
And for people that just need to move a lot, having it exposed to the open air is usually a dealbreaker. Panelvans are much more popular for that. Or MPVs with removable seats.
I have seen other countries where they are popular though. Like in Australia where they call it a "Ute". But yes also a long-distance country like you say.
Other parts of Australia do vary
As such things get bigger, get more doors, and veer towards a US size they get called crew cabs, trucks, pickup's, etc.
The wikipedia article: https://en.wikipedia.org/wiki/Ute_(vehicle)
Traditionally, the term referred to vehicles built on passenger car chassis and with the cargo tray integrated with the passenger body (coupé utility vehicles).
However, present-day usage of the term "ute" in Australian English and New Zealand English has expanded to include any vehicle with an open cargo area at the rear, which would be called a pickup truck in other countries.
They're all available with 4WD however.
Speaking for the UK at least, it's not like we were really getting US-originated models from Ford: it used to be the Mondeo or Fiesta but now it's the Kuga. Similarly GM (AKA Vauxhall/Opel, now Stellantis) pushed the Corsa/Astra and so on rather than, say, the Chevy Suburban.
A majority of them are made within Europe (if not necessarily the EU, between the UK and Turkey) so should avoid tariffs.
