I was thinking again about this...my thoughts are that even if I was going at a Flooded Mine pace down the road and would not need a belt, what if someone collided with me going PK pace?
I know it was outlandish to bring up the analogy in the first place, but as a teacher and coach ov "invincible 16 yrs olds with new driver's licenses" I field these issues alot, but true PK goes 60mph, so does your car, and you know you are going upsode down, so you buckle up...but if the ride was not predictable and you did not know what the path would look like, would you take your chances and go unrestrained?
