I've never understood safety standards for consumer goods. If you want to drive around in a horrible death trap of a car... why should the government stop you?
(Admittedly I guess you don't want driving time bombs, but the majority of NCAP standards are related to occupancy safety).
The same as you can trust that the carrots sold at a local supermarket do not contain arsenic - there are regulations against that. But according to your logic, it would be better if there were no regulations, surely a producer of arsenic-containing carrots will naturally go out of market after sufficient number of people die, because no one will buy their carrots anymore,right?
I believe that a car with a cabin that folds like origami in a crash should not be allowed to be sold in the EU(or in fact, anywhere).
