Jeepney
I was recently in Manila, Philippines and what caught my attention were the Jeepneys. These are a popular means of public transport like the autos of Chennai but are bigger and flamboyant.
Jeepneys were originally made from US military jeeps left over from World War II and are well known for their crowded seating.
Even though they are a law unto themselves and hardly follow any rules, all Jeepneys have this customary 'How is my driving' statement
