On the tarmac of a dark Hanoi street, motorbike taxi driver Pham Quoc Viet mops the bloodied knee of a fellow rider, one of the hundreds of traffic victims he’s tended to in the chaotically congested Vietnamese capital.

By day, Viet, 33, works for South-East Asian ride-hailing firm Grab, scooting along the tree-lined boulevards and winding alleys of the city.
