A 15 year old kid I knew back in Mexico worked for the garbage trucks, he'd hop off from the trucks side while it would slowly drive from house to house, he'd grab the trash from each house dump the trash inside the truck and he'd hop back on the side (while truck slowly moving).
Well he lost his footing when trying to hop back on and he fell inbetween the tires, getting run over by the rear tire. Being compact streets with people around, a man was signaling to the driver to stop because of what he saw. The driver still unaware actually backed up and ran over the kid again

.
Anyway this reminded me of that
The good thing is they could scrape him off the road and deposit him into the back of the garbage truck for easy, convenient disposal.
