"He was quite slow, so I tried to pass him into (Turn) 7. He drove himself off the track to make sure I drove off the track. Not sure of the point of that. It's stupid, in my opinion."He was really slow down the straight, and I just passed him, and then he just never stopped. It's a dangerous corner to try to do that. I would (say) that was an unsafe move. I don't understand it."Rasmussen disagreed with Dalys assessment of the wreck."Well, I think that's what you can expect to happen if you try to roll the outside in Turn 10, which is obviously the quickest corner on the track together with me being alongside him," he said.WHO IS ALEX PALOU?

Obviously the race control saw it the same way, so I don't know. Not much more to add to it."Rasmussen did take some of the blame, admitting that his wheel touched his side.Daly took one more shot at Rasmussen on social media before the day was finished."Purposefully wrecking someone in a 150mph corner is just pure insanity. Thats not racing. Its inexcusable. The driving standards, for some, are a joke right now. That means you (Rasmussen)," he wrote on X.Rasmussen finished in 12th, and Daly was 26th.Alex Palou finished in third place, wrapping up an IndyCar championship.
