Well, FWIW Bob Bondurant used to give a site tour to the students in a Ford van, I can't remember if it was 14 or 17 passenger but it was huge. When he got to the track, he said, "And here's where you will be doing laps!", put the hammer down, and took a lap at (as far as we could tell) full bore. Because we had a big group, there were other students following in the instructors' SHOs. They told us that the van's inside front tire looked like it was a foot off of the ground coming out of the corners! 😲 Bob was shuffling the big wheel and looked back at us and called, "Haven't rolled one yet!" My brother and I agreed that it was like that when you're a world-class driver. Of course, he had a garage right across the lot, and if the van had a mechanical problem he wasn't stuck towing/carrying tools across the country. So maybe not /exactly/ the same as racing the support vehicle....
