Back in its BA days early arrivals in T4 were towed into gates at the back of the terminal for noise abatement reasons and I have also been towed into/out of some tight gates at JFK.
Slowing down and taxying and then accurately positioning and stopping at the gate even with guidance systems in monster jets like 747/380s and 77Ws always looks one of the trickiest things for a pilot to do. judging the stopping seems hardest as often the plane almost stops then needs a bi of hefty shove on the thrust levers to move it another couple of feet . No doubt why they make that announcement about a complete stop and engines off.
