Agree what you are saying. I never forget to inform my paxs "to buckle up when ever seated" , period.
Still would help if it was made mandatory like in the road traffic.
Too many people get hurt without a real reason every year when as soon as they see the light go out to unbuckle in the hurry.
Have a look next time when you travel in the back, it looks like they are even in the hurry to do it!
