Somewhere there is a Senna vs. MSC split-screen comparo from non-simultaneous JP GPs. Senna was rowing with the shifter so his hand was sometimes off the wheel, MSC was using paddles instead and was a lot less busy then. Now MSC would be just as busy fidlding with buttons and knobs.
I can see an old-style brake bias lever, OK, but an entire video game on the wheel for the driver to dial in every little instant? I don't know if this is what the idea was behind racing or not.
