The grand master, Aryton Senna, did drive an F1 car around Monaco with his left hand on the wheel and his right hand on the stick.
I think paddle shifter got in production cars through Ferrari because F1 at the time started to convert to paddle shifter. A decade later, everyone copied Ferrari, minus the single clutch automated manual transmission.
I can't find it now, but I saw a youtube video of an F1 car getting out of the garage. The driver put the car in gear, grab the lower left corner of the steering with the right hand(to modulate the clutch paddle), then turn the wheel over with the right hand to the left 180 degrees while slipping the clutch. Imagine all those who claim that their automatic cars with paddle shifters are just like a manual trying that.
