What you say is true, Most drivers use the leg bags, and drivers to sweat alot in the car as the temp from the header is extream. At the time that i was referancing, this driver was in USAC. But the issue is from the time that they leave their haller, and get to the green flag can be a long time with all the people in the pits. this has helped with the rules about people inthe pits but the press is quite a pain. the time tabel can be from 1 hour to 3 hours and they are pumping them selves full of liquid to prevent dehydration. Needless to say i would still watch the lower half of the drivers during the interviews.
