Just make sure they have a red plate. Once they pull over offer them $200J for both of you to Alfred's and say it like you own the place. They are free to pick up others along the way, so keep that in mind. If you need additional piece of mind you can offer a driver sitting in front of CN $5 to take the two of you. It's up to them to decide if they want to accept it. If you like the driver get their number so you can call them for the return trip.
