Well, you must be thinking of something, I can't read your mind.
Here's what I asked
Please nominate three technologies that were developed specifically for F1 and then were used successfully in production cars. Or two. Or one.
Here's the previous list
Diacil cylinder? Developed for and used in motorbikes in 2002
CF body? Mclaren MP4 in 1981 . I suppose that might qualify, back then I don't think the aircraft industry was building entire assemblies out of it. Although in 1968 it was used in the VC10s.
Ceramic brake? developed for railway trains in 1988
Nitrogen tyres? Not worth doing
EBD? Developed at Teves in 1992, used in 2004 Dodge Durango if not before
Inconnel in road (not rocket)? Developed for Whittle in 1950s. Used in RX7
So, maybe 1, maybe.
