No one is "meant" to die. There's no such thing as the Grim Reaper. It just depends on if you want to die or not or how important/less important you see your life. Statistics show that wearing a seatbelts saves more lives than not wearing a seatbelt. Sure, you might get the shit-end of the stick, but STATISTICALLY wearing a seatbelt is better. Not wearing a seatbelt isn't acknowledging that if a death-scenario happened, it was your "time to die anyway." It's just not caring about your life or not believing a fatal crash could happen to you.
No one is meant to die. It just happens. If you want to fight it, wear your seatbelt. If you are apathetic to your living or don't think you could ever be in a fatal car accident, by all means, leave it off
