Jeepneys are a very common Philippine form of transportation along the lines of the US busline. They each follow a predefined route and for 7 pesos one can get on and get off at whatever point is needed. They are a really cost effective means to get around town as long as the routes take you close to where you want to go.
So far though, I have a tendency to get sick to my stomach while riding them. I suspect that this is a combination of the heat, the vehicle fumes, the low windows which force one to lean over low to see where we are, etc. I have always been an easy target for motion sickness so maybe it is just me.
