  • Both drivers initially climbed from their vehicles under their own power before receiving medical evaluations, with Rosenqvist reporting knee bruising but overall feeling ‘good’.
  • Race control halted the event with 13 laps remaining to remove debris and reinforce safety barriers around turn 3.
  • Drivers pointed to Detroit’s notoriously bumpy street circuit as a likely contributor to the mechanical failure.
  • The crash has reignited discussions within IndyCar about the stresses street courses place on both cars and drivers.
