So I strapped myself in the kids bench and flailed around, pushed, pulled, anyway I could move and I didn't go anywhere, to the point that I will probably have harness marks tomorrow. The belts didn't move, I didn't move. The worst thing that could have happened was a swinging arm would have clocked the person sitting next to me.
I think some of you have lost perception of reality.
A loose lap belt, yes I can see how that can create movement.
Rock bouncer recline, yes I can see how you would slide in your seat. I do not have a stupid recline.
Head clearance of one inch, yes I can see how you would stretch the harness enough to contact the cage. I have 6" clearance for myself.
Safety is one of those things that will be argued till the end of time. What one person thinks is safe, the next will think is unsafe.
If you obsess about safety too much, you end up in a bubble, in a padded room, in a straight jacket, eating sterilized meals, and your only stimulus is an echo chamber, which inevitably leads to your insanity.
Back to reality, I yell at the boys, is your harness tight, YES, YES, YES. Ok hold on, here we go, and we enjoy life.
