I'm not saying you're wrong, I haven't been to the tire wall day in the past. Do you have a link to the youtube video you saw?
The info on the website does say track touring for street cars. When we have run track touring in the past at BFR it has been street cars only, no helmets and a speed limit or pace car.
For this to be an HPDE type event they would need you to register, tech the cars, bring in corner working staff, have medical and rescue on site. I don't see them doing this for only two hours. I could be wrong though.
