I have a Singaporean friend who rides a motorcycle every day to work, and even he's appalled by the way his JHK colleagues ride - T-shirt, shorts, slippers, speeding in between lanes and weaving in and out of traffic.
He can't understand why life is so cheap, so disposable to the JHK - they work so hard, wake up at 5am to brave the Causeway jam every morning and the return home in the evening through another gridlock, just so that they can earn SGD to support their family back home. Yet they don't value their own lives, they don't realize that if they get killed or maimed in a bike accident there's no one else to put bread on the table.
It's ironic that low-income folk in Third World countries who have the most to lose have the least respect for life (their own & others'), while folks in developed countries would wear full-faced helmets, padded leather jackets, goggles, long pants and boots just to ride a bike.
