I guess if you've faced a tsunami and the odd monsoon going 3 abreast with a couple of tuktuks in the face of the oncoming traffic doesn't seem such a fatalistic risk?
I doubt a bunch of wealthy young chaps from Sri Lanka would be thinking even that far....just like they couldn't give a flying wotsit about the lives of everybody else on the road. Selfish idiots.
I doubt it too, but I reckon there is something behind social attitudes to risk. Back in '59 a world war was very much in living memory and we'd being living with the prospect of the next one being nuclear for just 10 years, seat belts were distinctly optional. Makes me wonder if it could even be quantifiable - could there be a fatality/risk constant?
