Like that killdozer where some dude (farmer? Can't remember) bought a bulldozer and fortified it and welded himself inside. He didn't go on a killing rampage, he had beef with the city and squashed loads of buildings.
As you said it came to an end when he couldn't move it. I think he got it stuck rather than running out of gas.

Years ago I had aanager who was really into road biking. Without going into detail, he came off his bike and took a hard hit to his head. He was wearing a helmet (and it would have been a good one, like most people into the sport do) but still had brain damage. He's very lucky that he made a full recovery. If he had no helmet he would be dead.
