I have never understood how they make the rules for what safety equipment the driver must wear...even for the slower cars. It makes no sense to me to require someone to have a jacket(of any kind) but not pants. Don't get me wrong I am not belly aching about that...just don't understand it. It seems to me that if anything were to happen that would warrant some sort of fire protection, your legs would need protected the same as your arms and body.Obviously you can wear em if you want to,but if they are so safety minded it seems odd that it isn't required.
