Considering the amount of effort they put into making them look lifelike, and move realistically, it certainly bemuses me that the way they are used in the sim.
For me, the tug rarely connects with the wheel, but starts going round the side, then magically reappears at the correct place. After the update, though, I once actually had him disappear completely while still managing to push me back.
Meanwhile, i was looking at one of the ground staff teetering on the back end of a truck, just interested in whether he’d fall off or not.
Then, taxiing to the runway, I had a car literally climb over the barrier to my left, crash onto the ground, but recover in time to dash across in front of me and go racing off goodness knows where.
It seems to be turning into the Keystone Cops (for those of you old enough to remember!), rather than achieving realism.
