Palou was not the only one whose race was stopped abruptly. On lap 83, Felix Rosenqvist and Louis Foster had a hard crash, leading to a red flag. Foster frustratedly explained the suspension of the car and the course’s conditions were the reason for the crash.

Sunday, Alex Palou ’s perfect season took a hit when David Malukas took him out of the race heading into turn one during a restart on the streets of Detroit, nudging the No. 10 Honda into the tire barrier on the outside wall.
