text: i have to make a persuasive essay on how seat belts are not good for your  any help post here?   persuasive answer against seatbelts? here is something to consider. the average car is designed for a person of at least 5', 6" in height. people under this height are in danger of being decapitated in a violent collison. i am under the height of 5' 6" and i find that wearing a seatbelt that crosses my neck, not my shoulder and chest is very uncomfortable and risky at the least. i have been fortunate to not have had any decapitation in my life (obviously) but i also no longer drive due to a personal accident from a few years back. and yes, i did have a welt on my neck for a while after my accident. hopes this helps in some slight manner, but look up the research and see if i am wrong. my source of information is both personal and from a documentary i saw on the cbc about 2 years ago. cbc - canadian broadcasting corportation.
