My car has plenty of buttons on the steering wheel, but unfortunately there's only so much real estate so you'll still need to fiddle in other places (ventilation and warming). And there are also menus, handled by the steering wheels buttons and displayed on the screen right in front of your nose but I still don't recommend that while driving as the menu structure was put together by throwing D12 dices on a drunk night out (luckily many menus are disabled while driving so there's less room for error)
