Why back up or do a u-turn? Where is your sense of adventure?

I cannot for the life of me, come up with a scenario where I would head down a steep unfamiliar hill in the dark.
Scene: Turn into antenna site to rest, contemplate life, hide, wait for friend, blow a doobie or make a simple u-turn. You get stuck and are unable to return to Lake Hughes Road. Figuring for a solo occupant.
Normal solution:
A. Call for help. Tow, CHP, Sheriffs, friend, parents.
B. You walk for help. Sub-station, rangers.
C. Maybe you can drive down. You walk down the hill and scout the terrain. ooops, big drop-off at the end. No can do.
D. Wait and flag someone down.
Not normal solution:
A. No terrain check...Go for it...Drive down and end up on the road on your side.
B. Walk down hill to check terrain, see drop-off and still decide to drive down. Ending up on the road on your side.
The in-between, not the smartest solution.
A. The car is stuck in soft dirt either parallel to or perp to slope. Get out move dirt from around traction tires and gravity takes over. Away she goes un-manned.
B. Turns into site comes down the right side of tower enclosure. As it gets steeper you say "DOH, this is steep better stop". However, you are on a steep slope and tall dry grass. When you hit the brakes...Nothing happens..Because you are skidding on the slick grass. You try to stop the forward momentum by turning the wheel left or right.. You roll one complete revolution, nose is pointing down. Holding on for dear life at this point, you end up on the road below.
C. Same scenario as B. Except when you realize that the car is not going to stop, you jump out. The car continues down the hill unmanned.
The tweener C. scenario is a strong possibility. Anyone who has driven a golf cart on an incline and hit the brakes knows what I'm talking about. Throw a little early mornig dew in...No stopping just sliding. I have both rolled a cart and jumped from a cart that was sliding on a hill. The B scenario there is a lot of brushy area where I would think the brakes would catchat some point before the drop-off.
