You’ve sat in traffic before, but it’s probably never been this bad. In Saturday’s NASCAR O’Reilly Series race at Naval Base Coronado, 25 cars were involved in a crash that ended up halting the event for more than 40 minutes. The accident occurred just after the restart for the final s tage, as Sam Mayer clipped the inside wall in turn one and bounced back into Anthony Alfredo’s car. Both drivers then slammed the wall and caused a massive pile-up on the narrow circuit, as they were running toward the front of the field when they crashed. Track workers spent the next 43 minutes and 10 seconds repairing a concrete wall that was pushed back several feet. No drivers were seriously injured, but Mayer, Alfredo and many others were out of the race due to significant damage.

I mean, I can’t be doing that. That’s just irresponsible, it’s embarrassing. I’ve got to be better.” NASCAR 3 hours ago Shane van Gisbergen on pole for NASCAR race on Coronado: Here's a full preview San Diego 15 hours ago From NASCAR to World cup, San Diego weekend packed with events This was the second red flag of the race after a manhole cover came loose and slammed through Corey Day’s front grill on the opening lap.
