“Unleash the bololô” – Laís Martins (restofworld)
“Named after the sound of a revving motorbike, these bololô protests have become a common tactic for delivery drivers in Brazil. Often, they’re used as a response to physical threats or racist attacks on the workers. Because drivers have little recourse for nasty customers on the apps that employ them, the bololô has become both a last resort and a rallying cry, drawing together drivers in a noisy show of solidarity”
