I was having fun for a few hours. Then I acquired a second vehicle. I had two drivers available, so I fueled up both cars and had each driver start up their vehicle. However, when I selected "escape" it left one vehicle and its occupants behind, resigning me to a quick short solitary death a few miles down the road. The game should have a very explicit warning that you're leaving without people as well as making it more clear you can't have more than one vehicle.
