Back in the day the world championship season invariably ended at Watkins Glen in October, but there was a time when there were also non-championship F1 races, and in November 1962 most teams gathered in Mexico City for the country's inaugural Gran Premio.
Ferrari, though, did not enter, and for the organisers this was potentially disastrous: for one thing, its absence detracted from event; more fundamentally, Ricardo Rodriguez de la Vega, already a national hero in Mexico at the age of 20, was a Ferrari driver.
Contracts were more malleable in those days. Rodriguez, desperate to race before his own people, asked Rob Walker if he could drive his Lotus 24 in Mexico, and instantly fell in love with the car, finding it way nimbler than the 'sharknose' Ferrari he had been driving. Fastest for most of the opening session, his time was beaten by John Surtees, and in the closing minutes he went out again.
