Yup. There's a lot of difference between what they show you on the TV commercials and movies and what happens out in the actual world. Having a Jeep usually means you get stuck farther from the highway than you would have in the car.
I remember helping a young couple change a tire a few years back. They didn't have a high lift jack or a shovel and were freaking out about how to get the Jeep ( Cherokee - one of the fancy ones with leather interior ) raised up with the factory jack ( wasn't going to happen where they were stuck ). I guess it took about a half hour or so to get them back up and running when they asked me if I had any water I could spare.
Sure enough, they took off driving with about a gallon of water between them ( it was August ) and that was gone by the time we finished. So I let them have some water and in the process we begin talking about how to get turned around and get back out of where they were.
Long story short - they didn't have food, they didn't have enough water, they didn't have a map of where we were, they didn't remember exactly how they got where they were or exactly how long it took them to get there. They only stopped because of the flat tire and figured the road had to come out somewhere. It didn't. The track they were on was a dead end and they would have found that out had they gotten to the end of it after another mile or so. They might well have ended up like your " eight is too many " Jeep story. We went slow and I led them back to the highway and I lived happily ever after. Not so sure about them.
