to me features like abs and airbags only makes 50 percent sensible to be made mandatory in vehicles. people sitting inside are safe what about pedestrians and vehicles which run over footpath and off-road . well these are subject of debate . it is same like in india cops are worried about passengers in car not wearing seat belt but they have'nt even thought about people in public bus and truck not even intaxi or trains .. what should be made mandatory is strict rule against illegal driving like under alcohol ,disrespecting road manners ,rash driving etc and of course better roads. that should solve most of issues on our soil.
