It is not so much how JFK is doing things as it is trying to fit a quart of widebodies into a pint of narrow body maneuvering area. To some extent virtual queues have reduced some congestion but the entire surface design, ramp, taxiways and runways is 'challenging'. Add into that running the airport at just over 105% capacity and incidents are bound to occur. Indeed it is a testament to the skills of tug-drivers, pilots and ground controllers that more ground incidents do not occur.
