first , no one have time to stop for ''seatbelt extender'' i would not spend a dinar on that  and no  its not about the extenders , its not confortable to have something squized around your body , because wether we liked or not , seatbelt lower belt is meant to be hardly attached around the abdomen \[ our belly \]  , we dont even like cloths of our sizes, we take an extra larger one above the one we're entended to wear just so you can have an idea,  lese9 lil bdan le , lezim mfarhad
