honestly straps could just attach nodes without having to do it manually, it gets annoying to carry a car that way, im pretty sure no one with more than room temperature IQ ever tried to put a car on a trailer and carry it without securing it first, and if you try to do it in the game the lack of straps to do so become noticeable.
What kind of physics do you expect from straps?? They are just supposed to attach stuff, if they had ultra realistic rope physics or something, it would be laggy for no reason lol
