“I don’t understand why they didn’t just mechanise a flap to cover the opening for FDuct to replace the rather unsafe driver hand off wheel method.”
because movable aero pieces or devices are/were banned is exactly why the driver operated the system with his body, combined with a very generous interpretation of “fresh air vent”.
i think they should stop screwing around and do it right – more powerful and varied use of kers and adjustable aero. the baby steps taken have proved the concepts, now open it up for progress.
if a car can save fuel weight by leaning on batteries for the full lap, i don’t see a problem. why shouldn’t a driver be able to tweak the front and rear wings to tune the car, or switch into low/high downforce mode? also needed is the ability to alter car settings on demand, instead of the once-per-lap sillyness.
