Bowman blew a corner on the first lap and spun out Wallace as a result. Obviously unintentional, but clearly Bowman was at fault and Wallace wasn't happy about it.
Wallace expresses his displeasure when they are together on the track again via his middle finger, and somehow this common gesture causes Bowman to see fit to wreck him again, intentionally. NASCAR and everyone else is well aware of it, as Bowman spelled it out on the radio. NASCAR takes no action and in fact protects Bowman by warning both drivers they are watching and to cut it out.
I see a lot of 'chicken****' behavior there, far more chicken**** than anything Wallace did later. The only person who didn't deserve to get caught up in the confrontation on pit road was the NASCAR medical director woman. That was unfortunate. Bowman deserved zero deference from Wallace given his actions, though he got some anyway, as it is obvious Wallace intended to do more than a drink in the face before he saw that Bowman was seated. The 'medical attention' angle as sympathy for Bowman is being exaggerated greatly. If Bowman wants to be left alone to recover after a tough race, all he'd have to do is not intentionally drive through people during it.
