Let's not kid ourselves: motorsport's major players, particularly those in Formula 1, have long permitted the sport to be used for political propaganda purposes, and any pretence to the contrary is disingenuous.
Forget Hitler's races, for proof look no further than apartheid South Africa. For many years F1, then effectively ruled by a Max Mosley and Bernie Ecclestone-dominated FOCA, was the only world sport to venture on the country's soil. The repressive government offered 'export marketing' (double) tax breaks to entities prepared to publicise the country, which were exploited then by sponsors and race promoters alike.
The 1985 South African GP, blighted by drivers and teams withdrawing on flimsy grounds to avoid controversy, was the last held before Nelson Mandela's release. Thereafter South Africa was struck off the calendar, but only after Australian cargo handlers refused to off-load F1's kit, proclaiming it 'tainted'. The race's replacement? The 1986 Hungarian Grand Prix, beyond the Iron Curtain, in a country under Soviet control...
Then, midway between Mandela's February 1990 walk to freedom and the country's first free elections a little over four years later, the still-racial country hosted 1992 and '93 grands prix under the banner of 'nation building' - coincidentally or not, South Africa has not since had F1 cars race on its soil.
