That issue just came up! Our 17-year-old son wanted to volunteer (with our car) to drive as many as five kids to a cabin a couple of hours away. Overnight. Because we have the vehicle that can hold the most cargo and the most passengers! He's a good driver, but we decided two passengers was plenty for him. No cell service, so communication isn't an issue...whether that's good or bad, I don't know. They definitely know how to get there, and one of the passengers is an EMT, I guess I won't worry (too much). Our son is responsible for the gas. I wonder if he'll ask for contributions from his passengers? Though one of them owns the cabin...
