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.
