F1: 5 of the most controversial moments of Schumacher's career

#4 Dangerous driving at the 2010 Hungarian Grand Prix

Schumacher was handed a 10-place grid penalty for the incident

After returning to the sport, while driving for Mercedes, Michael Schumacher was involved in a dangerous driving incident with his former teammate Rubens Barrichello.

The incident occurred on the main straight when the German squeezed the Brazilian when he attempted to pass him in the Mercedes machine. Barrichello tried to pass on the inside of the track, despite Schumacher trying his best to close him down.

Following the move, the German didn't allow enough space between him and the concrete barrier despite realising that Barrichello was positioned side-by-side. Rubens Barrichello pulled off the move and finished the race in the ninth place, one spot above Michael Schumacher.

The German was awarded a 10-place grid penalty for the next race for dangerous driving.
