Why no sleepers on UK trucks

Just lifted these from other threads, which kinda proves my point,.UK manufactured trucks with sleepers for the European market.

I’m maybe speaking from a 2019 perspective, but if I was driving before I actually was, and I was given the choice between a proper sleeper cab bunk, (modern by those day’s standards) kipping across the engine of a daycab on a board, or some dodgy B&B shared with strangers, I’d take the sleeper cab every time.
