Sebastian Vettel was furious with the stewards' decision which handed the Canadian Grand Prix to Mercedes driver Lewis Hamilton.
In an incident likely to be debated for a while, Vettel ran wide at Turn 4 on the 48th lap. In rejoining the track, Vettel squeezed Hamilton -- who had been in close proximity behind -- towards the wall, forcing the reigning world champion to brake heavily.
The incident was immediately investigated and Vettel was soon hit with a five-second time penalty. That meant he had to finish the race more than five seconds ahead of Hamilton to win the race, which he was unable to do.
