Suggestion: Possibility to download/add extra tiles directly from the program
Well, I don't know. Tapping directly into the Tesla servers is one of those things, that I would rather like to avoid, just to be safe. Besides, the architecture of the spline drawing is not really prepared to load too many tiles into it (just to preview a small region).
Have you also noticed that the "Radar Breaking Enabled" flag in splines of California tiles is now always false?
All tiles from the dev brach have F25 (Radar Braking Enabled) equal to zero. I saw F25 active only in the US live tiles. I don't know why it is like this, but remember that one of the possible reasons is that I was mistaken, and this flag can mean something else.
I looked at the road where I film my videoes, used the "daws" url. Is "daws" url the developer tiles, should I get them from another url?
In my videos, my "local winding road" is found in tile u4xth. Maridalsveien. As you can see, confidence is pretty high in the 90s but performance this autumn not up to par. The parking lot where I turn around is not mapped though.
The "local road with curbs" is Frysjaveien, crossing Kjelsåsveien over to Brekkeveien, tile u4xtj, and funny thing is that confidence drops from 99% to 3% suddenly in the crossing. Anyway, I have not been able to use autosteer since spring on that stretch.
My "local winding highway" is filmed with the most tricky parts in tile u4xt5, road 150. On this road I am not able to auto lane change, but still both F18, F24 and F27 are all "yes". I thought maybe one of them would indicate auto-lane change unavailable even if divided highway?
As scottf200 already explained, I believe you were looking at the dev branch. Directory part of the URL seems to be defining a branch (/dev/u4xth.tile, /live/u4xth.tile).
I don't really know what to think about the live branch in Europe. It looks to be quite old, because of their version string (like robertvg mentioned), because of the file date (http server says Last-Modified: Tue, 04 Apr 2017), but also because they contains only 25 fields instead of 27 (F26 and F27 are not just empty, it looks like the database serializer was not prepared for them at the time). F7, which I consider a Trust value, is always equal to zero, and F5 list (Blacklist) is not present. Maybe those tiles are not serving all their functions in Europe? There are indications about other map-like data sources for autopilot (like for speed limits or road classes).
Initially I thought that the function like enabling auto lane change will be clearly defined and easy to find in tiles, turns out it isn't. I don't know what more to say about it.
Did you already discuss one way streets?
Spline 61520267 and 61436357 in tile u4xth are, but no signs of any flag of such that differ from the ordinary local roads.
From what I've seen in maps a single spline is defining a route in a single direction. That means, that two way roads are defined by two parallel splines with opposite directions (lines of traffic in opposite directions are defined separately). Both splines you mentioned seem to be following this. There are only one spline above the road, and its direction is consistent with the direction of traffic shown on the google map. You can figure out the direction of the spline by looking which connecting splines are behind, and which in front of it (double click on list items in References tab), or by looking at the control vector directions.
There is of course the currentBranchIsBidirectional flag (found by verygreen) which confuses me. I don't know what it exactly means, but when I first saw it I thought it says that a single spline is bidirectional.
Some tiles with only 1 or 2 splines in it give a message:
WARNING: Found "Spline" structure with number of fields not in range 25...27
Which tiles are those? You might have found something new.
And BTW, I think I don't have to say that the viewer can have many bugs. One I found just after I posted it ("Acceleration" highlight is in range -5...5, but legend shows -10...10), but I don't want to create too many attachments, with too many versions, so I will wait for more stuff to be found before I post a fix.
