Some of my idotic friends who bought jdm cars like mira , alto etc dont wear sealt belts , when asked they say yar airbag khul gya to acha khasa kharcha ho jae ga .. On ko samjhana parta ha k j paise se ziada pyari chez zindagi ha , so this is the mentality of some people.
I my self have been in an accident and i have seen how much difference seat belts make ....
I have a strict habit of putting seat belt on even if i am sitting at the back , some people just don't know how much difference it makes.
Others think seat belts are not mandatory for shorter trips , they would say " yar yi sath hi to jana ha kya zaroorat ha seat belt ki"
Little do they know that impact of a car at 40kmph with a stationary object has enough force to smash their head on the windscreen, now imagine if the object that the car smashed into was also moving
