A Tut-Tut. It has a sign on top that reads "Taxi". Normally, you can tell the driver your destination and ask how much. Bargain and come to an agreement before getting on. There is no limit on the number of people you can squeeze on it. So squeeze! This is a much cheaper form of transport as compared to the actual taxi. But if the journey is too long, it can be very tiring if someone needs to sit on your lap. And especially so if that someone is very heavy-weight. Each trip costs between 30 - 70 baht, depending on distance and peak hour. No dependence on number of persons though.
