Windshield wipers -
Activating and using the Wipers requires too many touches and is a distraction to driving requiring the driver's eyes to be on the touch screen instead of the road ahead.
My recommendation - place the On / Off icon on the same screen and visual row as the choices for the icons I, II, III, IIII and Auto. Doing this will then allow for only one touch to select either OFF or the speed of the wipers.
AND - fix the auto mode so that it actually detects the density of the rain hitting the windshield sensor.
