local cars are a grey area, some deploy airbags with belts on, some deploy airbags with belts off,.. some have airbags and don't deploy,.. most don't have airbags.
airbags that go off without seatbelts can be fatal as they deply faster since they have to "catch" the occupants. airbags which are SRS deploy slower since the seatbelt is already slowing the occupant down.
anyone who drives without a seatbelt is a muppet,.. i've been saying it for all my life. who cares if your friends laugh,... at least you'll be around in a few years....
