Lewis Hamilton is concerned a dangerous precedent has been set after Sebastian Vettel was not penalised for driving erratically ahead of the first Safety Car restart at the Azerbaijan Grand Prix.
The Safety Car made two appearances during Sunday's race and the first came at the end of lap one after a series of accidents left cars and debris strewn across the track. Vettel was leading the race from Hamilton at the time and as the Safety Car returned to the pits on lap five ahead of the restart, it was down to the Ferrari driver to control the pace of the pack.
