The FIA Safety Commission and DaimlerChrysler safety experts have recommended its introduction in Formula One for next season. Several drivers in the CART FedEx Championship Series are currently wearing the HANS device. Just looking at the videotape of the tests will show you. I think it could be the same step forward in safety as when we switched from wearing leather helmets to the ones we have now. But I also want all of the drivers to have the chance to test it first this year, before it becomes mandatory.
Some drivers are particular about their comfort, and they have to try it and feel good about it.
