The scroll bar is on the right so this is intuitive to me.

Don’t think of it mimicking a scroll wheel, think of it mimicking a knob. The right side of the knob goes down when turning clockwise. If the scroll bar was on the left it would correspond to the left side of the knob and clockwise would be up (or at least should be).

I know not everyone would find this intuitive. My wife and I both bought the same make of car twice in a row (before wireless car play and android auto so we used the native ui) and the new ones moved the scroll bar on the infotainment from the left to the right, making clockwise change from up to down. I adapted in a day because it was obvious that moving a slightly curved bar on the right is clockwise for down but it frustrated my wife for several months until she got used to it.
