Pasithea

I once did something similar (Giving last rites to a dead animal, not running it over). Southbound San Tomas in San Jose, there squirrel was fatally injured and tossing about in the far right lane. I stopped the truck, put on flashers (The nice thing about a big truck. People pay attention when I block traffic- mostly), and once the squirrel stopped moving, I used a bag to put it on the side of the road, and give it a bit of a dirt covering.

It was all I really could do, but it actually felt good that I did it.
