did it for coachella two years ago, and it was awesome, needed someone to help with the gas and deal with the gps, made a new friend and he was incredibly trust worthy. I'm doing it again, from Calgary to Sasquatch. If you can meet the person or at least get a feel of what they are like, doesn't help
I am going for the whole festival and will be leaving when the festival is over, I haven't committed to what times I will be leaving, but I am flexible. I live in calgary and my car is super cheap on gas.
