No doubt the antics were ridiculous. Stenhouse should be ashamed.
I'm still unsure how the crash was Stenhouse's fault? He backed off to let Swindell slide in front of him, and then crossed over. He allowed room on the outside for Swindell, who visibly came down off the wall to make contact with him. Watching the few laps before leads me to believe that Swindell had no problem controlling his car. It was a calculated move on his part, obviously, to attempt to "block" the upcoming slider going into turn one. Unfortunately, Stenhouse was there and the contact resulted in damage to Stenhouse's car. That all is pretty obvious to me.
