Alex Palou isn’t comfortable with Iowa Speedway, which could have an impact on the IndyCar Series point standings after this weekend’s doubleheader at the .875-mile oval. Palou has been dominant all season, leading the standings with 417 points. He has four wins, with nine top-five finishes in 10 races. But Iowa Speedway, a fast short track that has gotten bumpier with age, has challenged Palou in his four previous races there.
