Sir Jackie Stewart says F1 tragedy 'just around the corner'

Three-time Formula 1 world champion Sir Jackie Stewart says the deaths of Dan Wheldon and Marco Simoncelli are "a wake-up call" for motorsport and says tragedy could be "just around the corner".

Formula 1 has not suffered a fatality since those of Ayrton Senna and Roland Ratzenberger at Imola in 1994, but reveals concerns about the amount of "liberties" taken by F1 drivers in the last couple of years and says the sport must not wait for another tragedy before taking further action.
