To me, any of the really early racing cars like the pre war Delages, Bugattis, Alfas, Le Mans Bentleys, etc. It took some serious guts to race them. Even today, when they’re raced in historic events, my hat goes off to the drivers.
Can’t resist putting up a picture of girlfriend piloting my Bugatti T35 (reproduction) . It is quite a pussy-cat to drive, but above 70mph very windy and skittish. No doubt the real ones are much more snorty.
