Fan hops fence during red-flagged NASCAR race at San Diego's Naval Base Coronado to meet a driver

NASCAR is in California this weekend for some street racing at San Diego's Naval Base Coronado, and one fan decided to really get close to the (thankfully, red-flagged) action.

The O'Reilly Auto Parts Series hit the track for its race on Saturday, and the race had more than its fair share of incidents.

The biggest came on a restart — because we all know that cautions breed cautions — and saw Sam Mayer take an absolutely monstrous hit.

The race was red-flagged, so crews could clean up the mess and inspect the barriers. While waiting on the track for the race to resume, Sheldon Creed, driver of the No. 00 Haas Factory Team car, unexpectedly got some company.

A fan scaled a fence, possibly several fences, to get to Creed, chatted with him for a moment, then took off back over the fences and into the crowd.

And he did it all in flip-flops.

You've got to hand it to him. The climbing in flip-flops was impressive.

Creed said on the radio that he thought his new pal was "wasted," which, let's be honest, tracks. It's not usually the sort of thing a sober person does, but innocent until proven guilty. That's what I always say!

Of course, it's a boneheaded move no matter how you slice it, and I don't think that guy will be coming back to more races this weekend or any other.

But, if this gave you a case of déjà vu, then you must be a longtime NASCAR fan.

You heard it alluded to in the clip from the broadcast, but back at Watkins Glen, N.Y., in 2007, a fan did the same thing during a red flag to score an autograph from Matt Kenseth.

By the way, isn't it weird how dated the "Car of Tomorrow" looks now?

But, hey, this is as good a time as any to remind fans that you shouldn't use red flags as your own makeshift meet-and-greet opportunity.
