I seem to be able to make quite a lot of money on both industry-to-industry service and passenger transport service, but there seems to be little to no money in delivering goods to the inside of cities. I only do it to grow the city to essentially get more passenger customers.

It's especially disappointing trying to supply cities with clothes, which seem to be worth a small fraction of what it cost to transport all of the constituent parts

Is this normal?

Newly purchased truck's first stop is at Forest Grove saw mill (top right), but instead of making a b-line to that stop by exiting the depot to the right, it goes left towards Lockport city (bottom left). Just curious why, it doesn't make sense.
