I'll leave my non-G-rated comment out of it. I know how you feel and my feelings are mutual.
To be fair, it could be that the crew finally fixed the commands to work properly. The problem is their fix, if you want, we can put the air quotes are around it " ", broke what we had already created. Not in all cases, but enough to be annoying.
The Drive to command is supposed to make the driver toe the line and wait patiently rather than find the quickest, but not always the most direct, path to their destination. The Navigate to command does just that and for the most part it works fine, especially out in the countryside where there's not a whole lot going on.
The problem is we've already built everything around the old behavior. On my very large route, I have about 200 miles if not more of mainlines, branches and yards. I have found that drivers tend to sit in some locations and back up rather than head to their next destination like they did before. To get around that, I had to put in extra track marks and use the Drive to track mark then Navigate to the next station instead of using Navigate to the next station directly. To make matters worse, it isn't all of the driver routes on this massive route. Some do it, some don't and I can't tell who has the problem until I take a ride with them.
On my very small but busy Gloucester Terminal route, a tram and freight operation about 7.5 miles long end to end not counting the docklands and branches, drivers will back up rather than sit patiently and wait in the queue to pull up to a station like they used to. In real life, this is quite common with trams as you know. I remember seeing this when I used to take the light rail in Boston for many years.
Now, I understand fixing bugs and whatnot to make operation smoother. That's what we pay them for through our purchases and subscriptions. What would be nice is if they could tell us that changes have been made or are going to be made before an update is released. This has been a common problem with N3V all along. The developers will "fix" something and tell us after the fact that they made the change with some cases being quite severe such as the most round with the throttle positions for electric locomotives that many of the Eastern European and Russian content creators are running into. The previous headache has left the Content Repair Group with a mess due to broken scripts. Without telling the community, signals, some MO-crossing assets, iPortal, and coupling scripts no longer work just to name some of the assets. To make matters worse, many of the original authors are no longer with us, sadly due to many reasons, and they had encrypted their scripts.
