My parents had a DAF33, and my in-laws a succession of
DAF66/Volvo66. Lovely things.
One of the great missed opportunities for the F1/road
crossover was the ban on the Williams CVT that Newey and
Head did in about 1992 --- Hill tested it, which makes it 91
or 92. It was massively faster than the rest of the cars at
the test on its first run --- and that _before_ the obvious
increase in engine power that would come from the powerband
being traded for power --- and was promptly banned. The
rules now mandate a minimum of two and maximum of seven
gears --- that avoids the old ``is a CVT one gear or an
infinity of gears'' dispute. Obviously the myth of the cars
that never were helps its reputation --- see also the six-
wheel Williams [*] --- but the idea is clearly sound.
Had Williams been allowed to race it, the credibility of CVT
would have hugely increased, as it would have blown the rest
of the field into the weeds. The old ``real men drive
manuals, it's the _control_ you know'' nonsense would have
been killed, Van Dorne would have been able to productionise
a credible high-performance CVT, cars would genuinely now be
different. Precious little of F1 technology will rub off
into road cars --- do you need 18000rpm? Carbon/carbon
brakes? --- but CVT would have been a real winner.
Great shame.

[*] 2 at the front, 4 at the back, like the still-born
March. Now holds the outright record at Goodwood Hillclimb,
driven by Palmer. The famous Tyrell P34 is now cleaning up
in Historic F1 and BOSS, engineered by the designer Derek
Gardner, because it has decent front tyres available from
Avon. What killed it in 1977 was the lack of fronts.
