Our first entry into third-world traffic was in this car hired for the day around Bandung. The driver carried a five-gallon container of water to splash on the regularly over-heating brakes whose linings had long since departed.
On major highways the number of lanes appeared to be set by an instantaneous and simultaneous calculation by all the drivers of the exact number of vehicles that could fit on the road abreast, plus one.
Here the truck takes his half of the road out of the middle while the moped driver with a child riding side-saddle already knows that nothing is coming the other way around the curve.
And that is diesel exhaust.
