Bernie Ecclestone has accused Indycar of playing with drivers' lives by organising "wrestling"-style races.
Briton Dan Wheldon was killed just over a week ago in a 15-car crash at Las Vegas speedway, a 1.5-mile oval whose event boasted Indy 500-like speeds.
"We would never have let that race take place in Las Vegas last week," F1 chief executive Bernie Ecclestone told the Daily Mail.
"With 34 cars racing on a 1.5-mile oval track, they were heading for disaster."
Wheldon started the race dead last and, in an Indycar season finale gimmick, he stood to share a $5 million prize with a fan if he carved through the field and won.
At the time of his crash, he had already passed ten cars.
It made the race a little like all-in wrestling -- with a high risk attachment
"It made the race a little like all-in wrestling -- with a high risk attachment," said Ecclestone, referring to British no-holds-barred professional wrestling.
"While our sympathies lie with Dan's family, the whole episode has not been good for motor sport in general."
