Don't know if other people do the same, but usually when I get into a new car I enable the virtual steering wheel via the menu, to line everything up with the real one and then switch it off again. A faster, more luxurious way would be a keybinding option (if possible).
They gonna have to add seperate PTP and DRS keybindings because of the DTM 2020 cars... That's a very good opportunity to add the show/hide Steeringwheel keybinding option as well... just saying
