[4][5] The final race of the series, the First Responder 175, saw a driving standards controversy.

With two laps to go, Pagenaud, who was slowing down, promptly collided with Norris, who was leading at the time of the incident.

Heading into the finish line, Santino Ferrucci took a hard left into then-leader Oliver Askew, who flipped; Scott McLaughlin crossed the finish line, from the pole.

Norris alleged that Pagenaud did so in order to prevent a non-IndyCar Series regular from winning the race;[14] McLaren CEO Zak Brown tweeted that what Pagenaud did was not something expected from a former Indy 500 champion.

Motorsport journalist Marshall Pruett later confirmed that an unnamed party involved in the incidents had also received death threats.
