…in eretz yisroel, and some chassideshe places here in america, women who sit up front or in teh back that have cros chest belts will put that behind them, which is beyond dangerous. the belt is manufactured in a way so that it is only going to work if both lap adnd chest belts are secure. venishmartem meod lenofshoseichem is completely lost on these people The reason I copied this here is to warn people. The seatbelt may be uncomftable or “un-Tzniusdik (are you kidding me?), either way, you must wear a seatbelt and wear it PROPERLY. Would you use a dangerous tool when a safety feature is not woring properly? The same is true for a car and seatbelts. (And if you would play with that tool, go immediately to the nearest mental institution and no, not in a car!)
