A Formula One car's steering wheel is the proof of how complex modern F1 cars have become. The "device" its self is a masterpiece of engineering, it allows drivers to adjust or activate all sorts of embedded electronic systems from engine torque differential and the pitlane speed limiter to KERS and even radio communication.. And who else than Michael schumacher can explain to us how the F1 steering wheel works? (except the people who designed it, the people who tested it and every other driver who speaks english on the grid, but you see the point right?..)
