I just saw a rabbit

Get shredded under some guys truck. It ran under the truck and bounced off one of the tires so hard it flew backwards to my car. I was able to get around it but I got a good view of it twitching and bloody. It's body was just..open...and it was clearly trying to breathe

I feel horrible for not stopping but I don't have a gun and don't know what else I could have done to help it... I can't get over it.
