Formula One should be tougher on drivers who impede others because "no one seems to care enough," McLaren's Lando Norris said on Thursday.
Red Bull's runaway championship leader Max Verstappen received three summons to the stewards in Singapore last weekend for impeding in qualifying and was handed two reprimands but no grid penalty.
Norris, a good friend of Verstappen, said the Dutch driver should certainly have been penalised for impeding AlphaTauri's Yuki Tsunoda.
"I think the blocking one on track was the one that should have been a penalty. He blocked someone," Norris said. "I know the team got the fine in the end of the day, but it should be down to the driver as well to look at his mirrors.
