Giving way to ambulances

You come across an ambulance on the road every once in a while. Yet in Singapore, people don't really get out of the way until the ambulance is right behind them.

When I was in Hawaii, we came across two ambulances (on separate occasions) while on the road. The moment people noticed the ambulance in the distant, cars pulled over to make way (in the midst of a traffic jam), allowing the ambulance an easy path through the crowded street. I guess we still have some way to go before we can call ourselves a gracious society.
