Bubba Wallace’s No. 6 Ford Mustang stock car overheated during today’s NASCAR Xfinity Series race at Road America, and decided it wanted to become an old-timey steam train instead.

Who needs a temperature gauge when a giant stack of steam can just rise out of the hood?

Fortunately for the steam engine’s conductor, Wallace got a free pass back onto the lead lap at the next caution.
