Stuck D-Horse in front of a road to stop a vehicle from passing by with a prisoner so I could ambush it.
They drove right over D-Horse.

1. Order D-Horse to defecate on the road.
2. Let the jeep pass by over the horse feces.
3. 
4. PROFIT!!!
While I admit I suffered from too much sandboxia to get very far in the actual plot of MGSV, I can tell you that I found this out and tried it myself and the results are satisfying. I donno what snake feeds that thing, but it must turn into some unholy mix of banana peels, animal birthing liquid, and whatever slip and slides are made of after passing through the digestive tract of that animal. A pile of horse crap should not do that to a car.
My own death: Playing warframe trying to help a friend grind parts for Equinox. In a underwater section and got pushed into the wall by a water jet. Got stuck and couldn't get out. The game's unstuck command did not help. The game is normally good about that, issues like this are rare, excepting specific areas, the place I was in being one of them, and normally you don't need the full team to complete an objective, and as long as half the party reaches the end it will consider the mission a success for everyone anyway after a short 1 minute delay.
This however is an assassination mission, a boss fight. And the boss won't spawn til everyone is in the room. I had to abandon the mission.
