These are common in all developing countries. In the Philippines it's called a Jeepney. They even did pop up around NYC, catering to Hispanic neighborhoods IIRC, and have been in various states of legality over the years. I think now they may be somewhat regulated.
In Thailand it’s called a Songthaew.
They coexist with an extensive mass transit system in Bangkok. In smaller cities and tourist towns it’s the only thing going besides taxis and such.
They are called Colectivos in Mexico.
