A General Motors executive who was driving the pace car that crashed and delayed the start of an IndyCar race in Detroit said Monday on social media that he let down his family and employer.

Mark Reuss was driving when the Corvette pace car spun and crashed into a wall during a pace lap Sunday, just before the race's scheduled start time. Team Chevy blamed the weather and track conditions.

Reuss is product development chief for Detroit-based GM.

His Facebook settings are private, but Forbes reported Monday that Reuss wrote: "I have driven this course many many many times. I have paced this race in the wet, cold, hot and calm.

"It is never a casual thing for me, but an honor to be asked. Today I let down my friends, my family, IndyCar, our city, and my company. Sorry does not describe it. I want to thank our engineers for providing me the safety I know is the best in the world.''

No one was seriously injured in the crash Sunday. It delayed the race about 30 minutes.

Ryan Hunter-Reay went on to win the race, his first IndyCar victory since 2015. He says the delay was "no big deal."
