Just watched a train derail in front of me for NO reason.

Do/Does the derailment(s) occur in roughly the same place each time? If so my first step would be to check the track for broken joins between the segments. My second step would be to check for incomplete track junctions (i.e. a small junction, usually involving a very short or hidden track segment, without a switch). I have had the odd occurrence of both and in builds prior to SP6.
I've created knotted tracks at spline points. These are invisible to us because they look fine, however, AI finds them and derails. This is caused by incorrectly connecting track at a spline point creating a switch that has one or two branches that go into the ground instead of no switch at all.
Sometimes, there are no junction levers and the AI will hit those and complain about a junction missing lever.
You should turn on message history and open up the driver messages so that they stream. Doing so will list all the driver's messages instead of showing a single line and allow you to see exactly what's going on at this point.
Hint: Usually, derailments are caused by user error I would say 99.999% of the time.

No, it's always happened at random points. I fixed one of the trains in that video only for it to derail again a short time later. At that point I decided to remove that train from my route. Just wasn't worth the trouble. Personally, I think some of @davesnow assets might be broken. That train derail three separate times. Twice including KCS hoppers made by @davesnow and some older boxcar content.

what's a normal map?
Nothing about what you are describing and attempting to show us seems to be related to specific train cars and it isn't likely that Dave's cars are different than default game traincars. It is pretty obvious though, that most of use have never experienced this other than the aforementioned suggestions.

Those suggestions NEVER work for me. I've tried that on every route with zero success. I've ran six passenger trains in the current session. All of them have made it across the entire route without incident. Three freight trains have derailed in random spots. Mine never did derail. All of the other trains I've dispatched trundled along without derailing. As for those @davesnow KCS hoppers I've used them in a different session. It was another route but still derailed so, something's up with them. If those hoppers derailing in different sessions on separate routes is just a coincidence, then I'm trying hard enough to identify the problem.
If that was the case, then ALL trains would derail upon hitting that broken joint or incomplete junction. That would include my trains operated by me. In fact, there's only four sets of crossovers and two spots where junctions exist. One is where the passenger station is separate from my mainline. Another spot is where an abandoned branch line joins the mainline.
Not doubting your words or efforts but I also had a similar problem - not derailing but the AI refusing to drive to the next destination when a manual drive worked.
I deleted the section of track (several segments) around where this issue occurred and discovered that at one segment there was another track directly beneath the one that I had laid. It had a deformed junction (no switch) where the two tracks joined. I have no idea how it got there (but probably I was to blame). When I later examined the original route (without the deleted and repaired track) I noticed that the spline point, in S20, at the faulty junction had a red dot (indicating a poorly formed Procedural track junction) instead of the normal black dot. If I had checked the end of segment dots along that section I would have noticed it earlier.

Ever since I started using auto drive that hasn't been a problem for me. So that can safely be ruled out. This is why I do test drives as evidenced by my progress report videos posted on YouTube. Now I'm the one operating those trains but also do AI test runs as well. For the AI test drives conducted by me, NONE have resulted in derailments or refusing to drive towards that next destination.

Just one example but this junction is clearly okay. The passenger train cleared without derailing. Now I've gotta do this for my other junctions.

Now three derailments occurred on this stretch of track as shown in my previous postings. The KCS train derailed in Fort Adams. I then put it back together and watched it derail again a short time later. While fixing the train that southbound NS movement derailed as well. Except after reassembling the train no other derailment occurred. In fact, no other train derailed at that location or any other place on the route. The track condition was labeled as good (75%). No incomplete junction, mission track or broken sections were detected.
Frankly, I much rather deal with trains derailing in the same spot regularly. That means there is a problem and it's much easier to identify and correct. When it's randomly occurring in different locations it's a much bigger challenge figuring out.

It might help if you posted the <kuid>s of those assets so that others could have a look.

Set up a consist with all of them and two locos (which seemed fitting). Placed them at the start of a long route with lots of tight curves, grades and poor track conditions. Started them running under AI to the opposite end (about a 3hr trip). Stopped the run at 1hr 31min and saved as a game to continue tomorrow (it is 11:30pm here now). So far no derailments.

We'll gladly take a look at your route and session. Upload them to the DLS or to a file sharing or online storage site and provide the link.
Sometimes, a fresh set of eyes will find the issue or even reaffirm the problem you are having. Others may even come up with a solution.
