[Fluff time] You are on a day and a half road trip, who are the top three worse travel companions?

Stretch your mind that you are on a trip, by vehicle, no jet, no train; you are stuck in a vehicle with them. Yes, you can imagine a motorhome or motor coach. Who would be the top three people you would not want to travel with, such as one who sweats easy and, you know, has BO, someone who has to give you the history of every landmark you pass if you care to know or not, someone who has to stop for some reason ever 30 miles or so, maybe someone has a problem with passing gas off nearly anything they eat, think of what would bug you and imagine having to travel for a day in a half with them, what type of top three people that bug you would they be?
