Ferrari Steering wheel paddle

[caseys]

So far this season Ferrari have intrigued me with their engine and electronics. The oil burn no longer burning and spitting out the back (seen quite a lot in bahrain under the lights).

The weird puffs/billows of smoke coming out of the garage as the cars exit the pits.

Think it's something akin to when McLaren had a double brake pedal? Something that's altering the exhaust? Or just something for the start procedures?
