When accidents happen in IndyCar racing drivers have nowhere to go but the wall, said former Formula One world champion Nigel Mansell, as the world of motor sports continued to come to terms with the death of Britain's Dan Wheldon. “In Indy racing, there is simply nowhere to go. When an accident happens you are into the wall in a split second,” Mansell told BBC Radio 5 live. “To have 34 cars travelling at 220mph on a mile-and-a-half long circuit, there are too many cars on the track. “The trouble is there are no small accidents when accidents happen. There were a number of rookie drivers and others driving in their first race of the season.” Mansell, who won the F1 world title in 1992 and the IndyCar title a year later, lauded Formula One for it safety measures. “This is why Formula 1 does an exemplary job,” he said. “The tarmac runs off so the driver has time to decelerate the car.” Red Bull Formula One driver Mark Webber said IndyCar would learn from the accident and look to make improvements. “I think the pack racing element of it is particularly hazardous,” Webber told reporters in Sydney.
