Fan arrested after walking onto NASCAR San Diego street course track

A red flag stoppage is supposed to be a controlled pause — marshals, safety crews, and drivers waiting for the track to be cleared. That a spectator in flip-flops could walk up to a stationary race car, have a chat, and exchange a fist-bump with Sheldon Creed before anyone intervened points to a meaningful gap in crowd-control execution at a temporary street circuit. Street courses bring their own security challenges compared to permanent facilities, but this went well beyond a fence-jumper being quickly intercepted. The arrest is the right outcome; the question the series will need to answer is how the breach got that far in the first place.
