That was by far the scariest car situation I have been in for a while. If I had been alone in the car I never would have found the menu item while driving and could have easily crashed before pulling over.
Even after we found two ways to adjust the wipers it was still the worst interface I have ever seen for a safety critical car system.
I usually spend a couple of minutes when I drive someone else's car to get familiar with the controls, as the rear window windscreen wiper, light controls (especially fog light) can be tricky on old cars as well.
I think the offset touch screen controls are categorically worse than traditional cars in many ways, but hiding the freaking windshield wipers is the worst of them.
