that's not entertaining, that's horrifying. however, it's clear that perspective is important -- if that were to happen within 50 miles of me, I have a good chance of being the person called out to the scene to do one of three very unpleasant things: find a dead horse; euthanize a horse with unimaginably terrible injuries; or attempt to extricate a live, terrified, thousand-pound animal from a metal and glass box and then treat it's unimaginably terrible injuries. and it's inconceivable that the driver would be uninjured, or that any passengers in the car would have escaped harm. I guess it's similar to the boat pictures -- to the boat owner, all they can see in the picture is the loss of property.
I suppose it's somewhat of a double standard to laugh at some of these pictures and condemn others, but I think that it's very possible that in the cactus picture, for example, after recovering from the initial event (assuming that it wasn't too serious), the person could look at that picture and laugh about it later. but with some of the other pictures, I can't imagine anyone involved ever being able to look at them after the fact and derive any amusement from them. so yeah, many people in the picture of the horse and the car very likely had a much worse day than you did: the driver and passengers of the car, the police and rescue officials on the scene of the accident, the driver of the horse trailer, the owner of the horse, the veterinarian called out to the scene, the cleanup crew who had to deal with the aftermath, and the horse. but really, does knowing that so many people had a terrible day make yours any better?
...or maybe vets just naturally become grumpy when shown pictures of animals in terrible situations.
