5 point harness in a car w/o roll cage...How to do it?

More typical intrusive American politician B.S. When Ferrari first started shipping the F40 to this country they had to remove the 5 point harnesses and replace them with the pathetic little electric thing that ran up the door frame and automatically belted you in. Oh that would make you feel SO much more safe in a 200 MPH car. They left the 5 points in the car so you could immediately trash the garbage mandated by brainless American politicians and re-install the harnesses.
