It can't, but it can create a situation where you are restrained to your seat in a rollover accident. Really depends on a lot of variables. The
seatbelt is not always the cause of the decapitation, just the restrained upright position. Depends on the age of the vehicle and other supplementary
restraints that may be installed. The older the vehicle, the more likely it has the potential to happen.

True bottom line here is the original seat belts are a DOT tested and
approved safety device like some other features of our coach. Any
deviation from a DOT approved device like this causes liability
implications to those who do it. Your insurance folks would not be happy
with a mod like that only if it caused unexpected results from a
collision-- can you say that cannot happen? If not don't do it, you are
not only betting your life but also your responsibility. NITSA has their
hands full right now with air bag issues along with so many more, I'm just
glad I don't design cars...
