I don't think it was DV or Abusive.
I DO think that if he had just left her the heck alone, let her have her freak out and get give herself a pep talk she would have gone down the slide. :-P His behavior was completely immature and unproductive but not abusive.
I completely understand crippling fear and I know that flipping out at someone who is already flipping out does NOTHING. I'm terrified of spiders, I CAN take care of them but if my DH was screaming at me "It's just a bug, you're doing all this over a bug" I'd shut down. (and would wonder why he's not taking care of it, if it's just a bug...LOL) but if I'm allowed to have my moment, stomp my feet, say a few choice words I can take care of the problem myself. But I have to be left completely alone and allowed to have my moment first.
ITA I am sure he was amped up on adrenaline too which made him seem desperate and harsh. You see how the stress of the race makes people mess up the simplest things.
I don't think he was coming from a place of intentional harm but rather trying to give her some tough love hoping that she would snap out of her fear spiral and do it.
I probably would have done the same thing (and ultimately threw her down)...
I have worked with domestic violence victims and their children for 15 years. I, myself, was a victim of domestic violence by my daughter's father.
This is not domestic violence in my opinion. We don't know what goes on behind closed doors with those two so I could and would never say anything for certain. BUT, if my partner did that I would totally lose it. I would have thrown a screaming fit which could not even be edited for television. It's a million dollars for crying out loud. She threw a terrible tantrum and should be embarrassed, I totally understood what he tried to do.
Me thinks he doth protest too much.
