Clarification... please?

We were at the Dallas D4 race last weekend, and upon tech, they checked my dad's neck collar as if it was manditory. However, some of the D4 racers, who are supposed to have them, didn't. No one questioned why they didn't have one, and one racer that I talked to, didn't even know it was manditory.

Another question...what is the best neck collar out there? The one my dad uses is so thick that he can't turn his head at all which made it impossible to see the other lane at the finish line, unless he was coming from behind. Also, during his first qualifying run, he actually had to stop against the right lane guardrail because he couldn't determine if it was safe to his left to turn onto the return road (from fear of being t-boned by the slower car that might not be able to make the turn for some reason). There's gotta be a thinner collar that allows for more head and neck movement from left to right. That would also avoid ripping it off as soon as he crossed the finish line, which is against the rules (Greg Anderson).

Any suggestions?
