If you use one you have to have a sternum strap other wise you body will crumple and con form to the shoulder straps thru loss of actual on the body tightness. I know we really don't like them at all. They also restrict rotation helmet movement enough you can see around you well enough causing more incidents. May be OK at big tracks but a quality collar is better in the bull rings.
If you would like to come by my booth at the Indy State Fair Grounds this weekend, I would gladly take the time to talk to you and educate you about the Hans Device. The words you speak here about it CAUSING Death, and Causing Crashes due to reduced visibility are due to you getting some bad info.
Tell me how that Quality Collar is going to keep the base of your brain from extending and separation from your spinal cord if you hit a solid object and go from lets say 50mph to 0 in a split second. A 50mph delta Z impact is quite possible in a "small bullring".......
Also, the improper use or location of a sternum strap, with a Hans can cause more problems due to riding to high on the chest, and then creating a close line during an impact when the body slides forward on the belts....Not pretty, and yes THAT would cause death.
I have been involved with the testing and development of the Hans since 2000. Is it perfect no......BUT I have talked to more drivers this past season that would not strap into a car with out one then not.
The most common error I see is the improper location of the shoulder belts when mounted to the cage. This can cause the belts to slip off, in a flip. However, as people get better informed, follow the installation directions, and take the proper steps in mounting the belts, they do no have that issue. Also, if they incorporate a way to stop the belts from sliding outboard, from the correct position on the cross brace they are mounting too, they will greatly reduce the chance of the belts ever coming off the Hans.
Drivers were not big fans of the Full Face Helmet in the early 70's either, but look at that progress...........
