To my best level of understanding, the "in a city" part above is totally
irrelevant, and certainly should be.

The check above is typical to determine is you have a transport type
so you know if you need to check for passengers in the current location.

Because of the somewhat brain-damaged IDLE code, units onboard a ship
may be idled at any time. They either need to resentry themselves, or
the ship may notice it is going to strand non-swimmers in the middle of 
the ocean, and will do it for them.

So, you need to be careful about when passengers think they are cruising.

I don't know exactly where you found this, but it may be used to deal
with cases where units are separated into transport types and non-transport
types for various other reasons as well.

For example if you found an IGTER in the OCEAN it would not move at IGTER
speeds, but at the speed of its transport (i.e. SINGLE_MOVE).
