One easy workaround is to just use trains for all your local deliveries. They're never one-way like trick stop drops, and, they feel pretty natural in the 1800s when the trucks can barely drag anything anyway, and you've got a lot of mail to move.

That is helpful to know, when i started using this mod a very long time ago. I had the same issue and didn't realise i had to use ugly goods depots inside my towns to allow the mod to function, these depots are as you put it ugly, and also very large. It looks awkward with 4 goods depots in tiny villages in order to catch every building and in some cases having to tear down half the town in order to build them... not to mention unrealistic. I would rather enjoy the idea of this mod having been built around a new industry building or a new roadside depot you could place that allows the pickup of goods, i know its possible to add new depots with this feature, not sure you can change the existing ones.

I'll admit I've never used the street side truck drop offs, since they are entirely unrealistic, and they were a bug that Urban Games left in Transport Fever to allow trucks to deliver to bus stops. Back in the TF1 days I was the lone voice who wanted that bug patched. My experience is that especially in the early game, I really only needed one or two truck stops to cover the entirety of the commercial and industrial demand for a city (while minimizing emissions), but given that residential buildings produce unsorted mail, I may need to rethink a pickup (and drop off) to cover residential.zones. I'm sure the workshop has some useful options that will fit perfectly within a residential area.

As a result, it ironically never changed my own game play, and the upside is that it's making my local delivery routes more profitable, since they can return with waste/mail.

When it comes to the transportation services the player provides, we are effectively doing terminal-to-terminal line haul for the bulk of cargo transportation. From there the catchment range provides the final mile delivery (there is a reason we don't have to select every single building in a town to deliver to). Roadside stops have no storage capacity, let alone any ability to allow the final mile postmen to pick up packages to deliver on their route. Larger cities are going to have multiple smaller terminals that allow them to service specific areas, though in residential areas, they are often smaller commercial buildings with a parking area to park the smaller parcel delivery vans that mail carriers operate out of.

In the real world, mail and packages get transported by transport trucks to a main distribution center, that then get loaded onto smaller vehicles to deliver the days mail to those smaller distribution centers. From there the mail is sorted and sent out on individual routes. In the game, we don't do that last step.

Despite some of the comments, you do not have to tear down half the city just to fit a normal truck station in. Just select a single 10m platform and you're good. It's not much larger than one of the larger town buildings. In Transport Fever there was a really tiny truck station mod that I did use, that was a fraction of the size of a normal truck station, since there really wasn't a smaller one-platform option in the game.
