Jonathan Legard says Dan Wheldon's death due to packed track and inexperienced drivers

The BBC's Jonathan Legard says the amount and the inexperience of the drivers may have led to the crash that killed British driver Dan Wheldon.

Legard says the race track was shorter than normal and the ingredients were there for something to go wrong.

Wheldon died following a massive accident at the Las Vegas Indy 300.
