For the TnT deals they also need to understand that the slick-tire guys have to be able to get to the slick lanes. They felt the need to block that - so you couldn't get there with the street cars not understanding lane designations or even that there were lanes painted on the blacktop.
The safety/cleanup crew also didn't understand how to get from the top of the track back to the starting line. Trying to get there by going into the back of the staging lanes and waiting for some cars to clear out was a disaster waiting to happen. I'm sure that was just because this was their first race - and quite possibly nobody told them how or where to get back.
