Jeez you realize how dangerous that is
U might as well wear no seat belt at all
It's dangerous, but not that dangerous.
It's mounted to the seatbolts...and if the seat bolts come undone, you are dead anyways.
Be aware that by doing ANYTHING in terms of modifcations to your safety systems may invalidation your insurance/warranties.
If you get into a crash, and the seat belt fails due to a owner modifacation, your insurance company will not be responible for it's affects.
