Good question, Jonnyxx! I think 14B too. Frankly, I've never had the opportunity to get stuck and try to enjoy it. Some factor-- usually more than one-- was missing. Wrong vehicle, in a hurry, in too public a place, or on the other hand too far from help, etc. Always something. Even if I did enjoy it, I'd probably fantasize that someone else were driving. The most promising occasion was a snow stuck in the driveway of a friend who lived just outside of town. I'd knocked on the door. No one was home, and I didn't know when he would return. When I went to the car to leave, I got stuck turning around. He was one I'd really love to see tackle the challenge (14B in an instant!) But on balance, I was glad to drive away after a minute or two.
But I know I enjoy watching a cute guy stuck because, well, look at the stuff posted here and elsewhere that I feast my eyes on. A few times I've gotten stuck with potential sweethearts in the passenger seat. I chose B immediately. I hope it was as much fun for them as it was for me. Wish I had asked them afterwords. I'm I <gasp> a voyeur?
We can also bear in mind that with B, in a way you are the one in control. What your friend does is obvious, and since it's your car (oops, am I assuming too much here? The question doesn't actually specify who is driving originally. So, IF it's your car), you can give him instructions along the way. But he has no idea what you're doing. You can say that you are going to push, but it's up to you how hard . Pushing is probably easy to fake, even if you must appear to be pushing with all your might.
