Although run to a completely different set of rules, the Indianapolis 500 was part of the FIAFormula One World Championship from 1950 through 1960. Drivers competing at Indy during those years were credited with World Championship points and participation. Chet Miller participated in 2 World Championship races - the 1951 and 1952 Indianapolis 500. He retired from both races, therefore scoring no championship points.
With his death during practice for the 1953 Indianapolis 500, Miller became the first driver to die as a result of a crash during a World Championship event, and the second driver to die either in a Formula One car or at a World Championship event, after Englishman Cameron Earl had died 11 months earlier while testing an ERA Formula One car at the MIRA proving ground in England.
