Do steering wheel designs (not in terms of button positions, but in terms of the wheel shape? For example, we see the Ferrari and the McLaren having an actually similar-ish shape. However, the Red Bull wheel is a very aggressive looking x-shape. Then again however, the wheel designs have changed too. button/hamilton's steering wheel looks quite different from the one Alonso/Hamilton's McLaren had. Just wondering if this actually was somehow designed in terms of aero as well.
I never knew, however, that the wheel was tailored to suit drivers, as this video shows
