Well - there ARE exceptions about not buckling up - and I'm living example.
November 1973 - I was not very experienced car driver - we came from swimming hall w my friend - I was driving Morris Mini wo seatbelts. I lost control on a slippery spot and collided w a lorry+trailor combination. At the moment of collision my car was sideways in front of trucks left corner. Nose of Mini shifted about 2ft to the left and ripped right-side door with it. My friend flew out and broke his arm. Mini then roled over few times and the roof came in about one ft. I had fallen sideways to my friends place w my legs still on my side.
When I came to my senses I thought the car might catch fire - took the keys and crept out - world was dizzy and swaying so I laid on my back in the middle of the street. I somehow knew I should not try to move more - so I just twisted all my joints to check if they're ok.
While laying there - light snowfall - a man w hat bowed over me and asked : Do you think it is time to pray? - I told him it is not - and even if it were I was not going to pray with him. He replied : "You never know!" - later I saw my face in the mirror - I had long hair and it all was covered w blood - I had a relatively small wound on my head - but lots of blood.
Some people came and I asked about my friend - they said he lays over there and complains - I thought : Oh good - he comlains - he is alive. After fairly long wait two ambulances arrived on the scene. They put me on strechers - and while they were carrying me I was turning my head to look around.
The ambulance driver apologized for it taking so long for them - the weather was really horrible and he had to stop to help the other ambulance out of snow.
Next day my friend told me a hilarious story - his father had a collegue who passed that scene - and told him next day at work : " I saw this horrible wreck - Truck laying on it's side - a wreckeded car in close to 30 yard long row of shredded parts - I though they all were dead for sure - but lo and behold - one person on stretcher was moving his head ! " The father told the guy, that the other guy on other stretcher was his son
Few days later I noticed that something is glowing in my chin - there was a square piece of glass nicely imbedded into my skin - I took it off and it left a square hole - put the piece of glass back again and had short discussion with me about having it there and becoming "human puzzle" - then decided it has to go.
Ever since I use seatbelts - no matter how short distance to drive.
And ever since - no matter how fancy car - it is only piece of materials put together.
Drive safely yall
