This doesn't involve critters making nests in vehicles, but a friend of my family used to have a dog that would
frequently, as a matter of habit, take a nap with his head resting right behind the rear tire of the farm pickup. He got his HEAD run over several times when someone wasn't paying attention. Thank goodness the truck was always parked in a soft dirt driveway. The dog was never hurt; he just shook his head and ran off each time.
This was the same dog who got beaten up by a raccoon, kicked by a cow, and tangled in an electric fence. True story.
He died of natural causes at age 17.
And no, his name was not "Lucky".
