Michael Schumacher would have been disqualified from Sunday's Hungarian Grand Prix if his risky move on Rubens Barrichello had been earlier in the race, steward Derek Warwick said Tuesday. Warwick, a retired Formula One racer acting as the drivers' representative on the four-man stewards panel at the Hungaroring, told BBC radio that the seven-time world champion should have been shown a black flag for almost driving the Brazilian into the pit lane wall. Instead the former Ferrari ace, making a comeback with Mercedes after three years out and at the age of 41, was handed a 10-place penalty on the starting grid for his favourite Belgian Grand Prix at Spa-Francorchamps this month. “Throwing a black flag would have shown a better example to our young drivers,” said Warwick, who overlapped with Schumacher in Formula One for one season in 1993 when the Briton drove for the Footwork team. “But by the time we got the video evidence we ran out of time and we had to do it retrospectively.” Schumacher made a rare apology to his former Ferrari teammate Monday.
