Norris said: “Could I have at times made maybe better decisions? I think so.
“I wouldn’t say I regret it. But do I wish I could do it better and do it again, yeah. But I don’t regret making those decisions at the time. That’s life.
“Sometimes it goes your way and you get lucky and sometimes it goes the other way and you don’t make the best decisions but those are the times you learn the most.”
Norris acknowledged also that other events had played a part in his deficit not being bigger than it is.
This is a reference to Piastri losing the wins at Silverstone and Hungary. In Silverstone, the Australian received a controversial penalty for braking behind the safety car, and in Hungary Norris was able to recover from a bad start by switching to a one-stop strategy mid-race that even he at the time did not think would get him the win.
Norris said: “I have certainly had a little bit of luck. I have also been unlucky. But that is life. I can’t change those things.
“This year I’ve had a car that I’ve found a lot trickier to drive but I have made some good steps forward to come back and improve and I would not have won in Budapest if I had not improved in that way.
“I have also made good decisions and kept myself out of trouble, stuck by the rules. All those things are part of being a racing driver and at times they have gained me points. That’s down to me doing a good job at times.”
Piastri would be leading the championship by 37 points if he had won in Silverstone and Budapest rather than Norris.
But he said: “I certainly don’t feel hard done by.
“There’s always going to be things in racing that you don’t necessarily agree with or don’t go the way you want and that’s just part of it. Sometimes it makes you wonder where you can just edge forward.
“We’ve done a lot of things well that we can control this year. There’s been some tough moments and tough lessons, but I’m very confident with the position that I’m in.
“I feel like I’ve driven well this year. So yeah, there is an alternate universe where a lot of things look very different, but none of that matters.”
Both drivers said the team would continue with their policy of allowing them to race each other, including the option of picking different strategies.
