"proper tightness" or not doing any good?? really? you could have visible slack, i contend that holding both shoulders will still keep you more secure than any 3pt could ever hope to.

if you are racing and could hit the wall at 200mph flipping 10x thru the air, yeah, wrench that sh!t down crazy-tight. if you are driving thru town on your way to Walmart, what tightness would you put a basic lap belt at? shoulder belts are similar without slack, but still allow you to breath normally.
