Display MoreGonna climb up on the soapbox here ........
Notice ( as @mniron mentioned ) the head restraints on the seats combined with all occupants also wearing HANS devices .....
Without head restraint the risk of breaking your neck or separating your skull from your spine is greater than the perceived added protection with a harness alone ...
The stock three point belt is designed to slow forward movement and rotate the body for less stress on the neck and spine.
While nothing is perfect for all conditions harnesses are for the track and a liability on the street if other supporting restraints are not used, I challenge anyone to find reliable, professional information to the contrary .....
Gonna let y'all hash it out if you wish but urge you to seek facts rather than opinions or feelings ......
I stated no facts, only my feelings. HANS device wouldn't work for me because I don't particularly care for wearing a helmet all/most the time. Your attached photo is informative.
