Some of the highly publicized tech on pricier cars is quite old hat.
I have a gun sight from a Spitfire, still in it's original box, that used the principle of the HUD. You can set the illuminated circle on the glass to match the wingspan of a particular aircraft at a pre designated range. This was the pilot's firing point, assuming he'd made allowances for deflection.
We remember Vettel's dominance in the era of blown diffusers. When the spitfire first flew, RJMitchell had allowed the exhausts to come straight out of the engine cowling, at right angles to the slipstream. He engineered some proper exhaust stubs angled towards the slipstream that gave an immediate speed increase.
