Well, I made some attempts but I ended up wandering around with no clue of where to go, continuously getting stuck in rocks or craters. I expected something at least when I ran out of fuel, but the game didn't bring me to an end nor the vehicle stopped, so I eventually ran into...the starting base.
The cinematic at the beginning of the game is supposed (I think) to show the way to the player, but the camera movements are too much confusing, making the shot not much enjoyable.
Would have loved to see the other endings, besides the "wait ten minutes" one.
