   It's the size of the thing.  I've also read that pilots upgrading to
   the 747 have to be warned about taxiing too fast.

Now that you mention it, once we were on the ground and taxiing,
the flight engineer repeatedly called out the ground speed, even
when we were in the middle of a taxiway with hundreds of feet
of nothing in front of us.

The captain kept the 747 rolling at a maximum ground speed of
4 knots, slowing to 2 about 200 feet out from the gate, and
then to 1 as we got to maybe 50 feet away.
