IndyCar drivers have led this incredible tribute to Justin Wilson, a driver who died after sustaining injuries during a race last week.
Travelling across the Golden Gate Bridge in San Francisco, the drivers carry on in formation in front of hundreds of people.
Wilson was injured whilst racing in the ABC Supply 500 race at Pocono Raceway, Pennsylvania.
He was hurt when another car at the front of the race, driven by Sage Karam, crashed and scattered debris across the track.
Whilst attempting to avoid the debris, Wilson was struck in the head by the nose cone section of the car that had crashed and was taken to hospital by helicopter with severe head injuries.
This is the second time in four years that IndyCar has lost a driver, with two-time Indianapolis 500 winner Dan Wheeldon passing away after sustaining injuries during a crash in 2011. This has prompted officials to look into the safety around the sport.
