And just a quick note to fill you in about Biondetti, Luca:
Monza was his only WDC start, but he started racing motorbikes in 1923 and switched to cars in 1927. By 1931 he was a works Maserati driver. He later moved to Alfa Romeo where his reputation grew and he was the only man who could live with the Silver Arrows in the 1937 Tripoli GP - check out the speeds in that race!!!
Biondetti's real forte though was the punishing Mille Miglia, which he won four times: 1938, 1947, 1948 & 1949. He also won the difficult Tour of Sicily twice. He finally retired in 1954, aged 56, having placed fourth in his last Mille Miglia. He died of cancer the following year.
