Bob Pockrass: "NASCAR is exploring whether to eliminate jackmen from pit stops by equipping the cars with air-jack systems. The sanctioning body, which often considers a variety of changes at this time of year but doesn't necessarily implement all of them, won't confirm how far along it is in the process nor any timetable for a decision. The change, which would reduce the number of crewmen on pit road during pit stops, could potentially save teams money, depending on how much the system costs as well as any development on how it changes the handling of the car."
I'm opposed. Nascar pit stops are perfect, and constitute an important part of the competition and the show. No other racing series has the situation where pit road performance by the crew is important in the race. I like it being important. Also, I'm concerned about air jacks on damaged cars and other unintended consequences. Just my $0.02.
