My stand on this subject, and availale options:
No roll bar, OE belts only or DOT harness
You may install a non halo seat

Roll bar, all current options
Actually Scott, I believe NASA TT has passing during competition, something we have repeatedly avoided. Car to Car contact risk has to be much higher. I think our rules are much closer to HPDE than NASA TT (Haven't looked into the SCCA)

On the other side of the coin, if harnesses are not safe in cars with pretty good structure, why do we allow them in convertibles with just a roll bar? My concern is that our rules are not consistent. Either allow drivers to make their own choices or mandate the toughest standards equivalent to race for use of a harness. I don't see Spec Miatas with just a bar.

Your concern re use of harnesses in old cars is perfectly valid but could be dealt with by the scrutineer. OTOH, telling someone that they cannot use a known safety device (head and neck restraint) because "we know better" sure needs some data to be substantiated particularly given what I see as the inconsistency of our rules. Not really sure which is the riskier approach.
