Drivers used to have to drive around Monaco one-handed in the days of manual transmissions, none complained they were too busy in the cockpit then. If the more hectic cockpit increases the possibility of driver errors like in the old days drivers could miss a gear etc. then that's only a good thing.
Of course this doesn't have anything to do with my opinion on the adjustable wings which I think are an absolute joke. I'd have nothing against allowing adjustable wings but this thing that you can only use it if you are 2 seconds behind a car and only twice a lap etc. etc. is just BS of the highest order.
