Can't hear a darn thing from either video, but from what I can see it was handled as well as any random, crazy situation could be. It could have been much worse. The horse could have been tangled in it's own lines, or tangled into one of the other carted horses it barreled into out of panicky fear. Since horses have a blind spot directly in front of them and the eye guards (I can't remember what they're really called), I can kinda see how the horse ended up running into a couple of fellow equines (not to mention it's panicked state of mind). At least everyone came out alright!
