The confusion may come from its age; newer sets seem to use a smaller one (part 98282) <https://www.bricklink.com/v2/catalog/catalogitem.page?P=98282#T=C>

@RSchulz Out of 11 sets using 50745 element in 2021, 6 sets have it in White. I'd say this wheel arch (50745) is still pretty common these days.

Huh. Only 10 of the smaller one in 2021. I just assumed when they changed the mold, they'd go all in.
