Lewis Hamilton said he felt fortunate to be alive after a collision with Formula One title rival Max Verstappen at the Italian Grand Prix on Sunday.
Stewards handed Red Bull's Verstappen, the championship leader, a three-place grid penalty for the next round in Russia after his car landed on top of Hamilton's Mercedes, with the rear tire hitting the champion's head.
The halo protection device, a titanium ring around the cockpit, took most of the impact in a crash that left both drivers out of the race at Monza.
