…drive on the pavement.
I first went to Saigon (Ho Chi Min City or HCMC – but Saigon as in Bia Sai Gon or the Saigon River) in 1991; then there were a few cars, smoke belching buses and the rest was 90% bicycles, 10% mopeds. Now it’s 90% mopeds and the city’s roads are overcrowded, not least around the heavy construction works for the impending new metro.
There are few rules of the road, red lights aren’t obligatory or advisory – they are ignored. The mopeds just want to keep on moving, so road or pavement, anything goes.
