So some cyclist died and his friend wrote to the minister asking for a 1.5m bicycle lane.
If you watch the video above and think that drivers are driving badly, perhaps you've missed the point. They are driving normally, badly is the normally in Singapore.
Drivers do not give a damn about bicyclists on the roads. They don't care about other drivers. They even ignore basic stuff like signalling before changing lanes.
If a traffic accident happens, it's just a traffic accident. It's not a criminal offense. You break an arm or leg, or lose your life in a worst case scenario but the driver will only get a fine, maybe have their driving license suspended.
I will be surprised if the cyclist who posted the video don't die on the road if he/she continues riding like that. Not through his/her own fault, but you can never underestimate how callousness drivers can be.
How many more should die before action is taken?
As many as it takes to make it statistically significant.
