Good point. It was the silver car that overcorrected somehow as a result of what happened prior to video start, which we don’t see. Although the truck driver may have nudged the silver car beforehand, the truck driver did his best to minimize the carnage.
Sorry to beat a dead horse, but I’m going to speculate that the silver car failed to negotiate the curve in the freeway, causing a last minute correction into his/her lane, resulting in the overcorrection that slammed the truck. Okay, I’m done with this post. LOL
