Sergio Perez has criticized Pastor Maldonado as a "dangerous" and "stupid" driver and feels it is time the stewards finally threw the book at him before another driver is hurt.

For the second successive grand prix Maldonado faces a post-race investigation, on this occasion shoving Perez off track early in the British event at Silverstone.

Just a fortnight ago Maldonado punted McLaren's Lewis Hamilton out of the European Grand Prix on the penultimate lap in Valencia, and yet under the rules was only given a retrospective drive-through penalty.

On this occasion a furious Perez feels Maldonado should be given the kind of penalty that will teach him a lesson.

"He didn't give me any room," said Perez of their incident going into Brooklands on lap 12 where the Sauber driver spun off.

"He has no respect for other drivers. It's the way he is driving.

"I made the same move on (Jenson) Button, and he rightly fought me hard, but he gave me the room."

Perez added: "He (Maldonado) is a very stupid driver. He ran Hamilton out of the race in Valencia.

"I don't know why the stewards don't take more action against him. He deserves a big penalty.

"We are risking our lives out there and if they (the stewards) don't do something he will hurt someone.

"For all the drivers he is very dangerous driver on the circuit."
