ON Wednesday last week, the sun had not been up for long in Hanoi, Vietnam, but the streets were already full of vehicles-much like Jakarta on a work day. "The difference is, people here like to honk," said Ameidyo Daud, an Indonesian journalist in Vietnam.

Amid the crowded streets, dozens of Go-Viet drivers wearing uniforms dominated in red make their ways around city.

That Wednesday was the first day for Go-Viet to operate officially in Hanoi.
