When you are on the way through Jakarta, you see really weird and funny transportation variations. Here in Germany you think, you always need a car for transporting a washing machine?! No you don´t, but if you try this in Germany, I think you have to pay.
In Indonesia, no one says, it is impossible to carry anything on a motorcycle.
And for animals of course you need a bigger vehicle. A pick up car is enough, just like you can see here a cow and three buffaloes. Just watch and enjoy!
