There are many, many people who live in Indonesia, especially in the city that I live in. The roads are very busy and being on a motorbike makes it much easier and quicker to get around traffic. It's also much easier to find parking when you are on a motorbike. For many families, a motorbike is their only type of transportation so people are very creative when figuring out how to fit their whole family along with some purchased items onto just one bike!
