What I find quite strange though is - when my GPS antenna wire was broken (frustratingly days after delivery), understandably both nav systems (and any browser location based services) decided I was stationary wherever I drove. TechSupport at the time confirmed all other data came in as expected when driving (gyro, etc) and the SvC later reported the loose GPS connection from the logs showed at most 1 lock, so I never got a GPS fix hence me being stationary for anything relating to location awareness - all makes sense to me.

What I do not understand is why my AP(1) functioned absolutely fine during that time - and acted no different once the GPS issue was fixed either.
I don't believe any of the current AP features have any dependency on GPS. Why would they? The car reads speed limits off road signs, and Autosteer and TACC are entirely based on processing the data from onboard sensors.

@arg has anyone pinned down the "in-house" foundations. I'm presuming they forked it off one of the open source navigation projects.
My understanding (from a reasonably reliable source) is that the built-in satnav system is Navigon, but that starting in (?) v6.2 Tesla switched out the Navigon routing module for their own. So the maps are still Navigon, the instructions are still Navigon, the audio announcement files are still Navigon, the diagrams of junctions are still Navigon, the offline address database is still Navigon; it's just the routing engine itself that they moved to use their own code.

I don't know how route via superchargers works. Does it need internet connectivity? Does it adapt dynamically (i.e. suggest a different set of stops) based on traffic, or once you're on a trip does it think only about the next leg? Personally this is something I'd calculate on a server farm somewhere and then pass a waypoint list back to the car to render and provide the details.

The really absurd routes like the ones above are, I agree, likely to be gross errors in the traffic data - but I don't think they occur very often and I'm not sure they occur significantly more often than other navigation providers.
These are pretty much the only class of issue I notice. I can believe that sometimes the car's suggested route isn't optimal (and maybe google or waze would do better), but that's not that noticeable.

It still does off-at-one-junction, on-at-the-next detours, and similar rat-runs through back streets - where the obvious route is up to a junction and turn left, it's keen to turn right and take a back road up to the cross-route to overtake the queue of cars in front of you. These can occasionally be nifty shortcuts, but usually end up taking longer due to the queue at minor junctions that probably doesn't show in the traffic data. I think this has decreased lately, but it's still there - probably they've tweaked the weighting factors a bit.

It's been said to have map-based support (and that the learning is map-based). I don't know how true that is, but obviously it would still work without, to the same level of quality as before it had a chance to learn.

Yep - to me at least the whole 'deep learning' thing requires a functioning GPS - maybe the learning is not that deep :)

Georg said that Waze is the gold standard of routing, and that's what they are going to try and achieve.

Frankly, if it were paying 50 quid a year for Waze routing I would probably do it.

Any learning that goes on happens outside the car, based on data sent back to the mothership. If the GPS is not working I guess none of that data is collected, but that's not going to impact how your car is currently driving.

Yes if there's a cheat sheet of "just up here it looks like a 40 degree bend but actually it's 50 degrees; watch out" that won't be available without GPS, but clearly AP is capable of driving on roads that no Tesla has ever driven down before, so that stuff isn't mandatory.

We are just back from a trip to France where we experienced a couple of classics examples of Tesla navigation that seemed to be a good fit for this thread.

The first suggesting a route from a Dover ferry terminal 'waiting lane' to the ship itself...

And the second an imaginative alternative to a left hand turn in a Vosge village...

There have been recent rumours of Tesla switching to a combination of Mapbox map data and the opensource routing engine Valhalla from MapZen. Both are companies that work mainly with OpenStreetMap Data ...

Especially Mapbox have massive VC funding to build up their database and are hiring like crazy capable GeoData specialists.

Oh, don't worry this is standard.

It goes spastic for about half an hour every time you've magically moved it on a ship or train across water.

One time I had the thing consider itself in Portsmouth for about an hour, when the car was firmly in northern Spain.

Elon says new nav is rolling out soon...via Twitter...

"New nav starts rolling out this weekend. Should be considered a mature beta at first, so won’t be perfect, but will improve rapidly. With the old system, we were stuck with legacy 3rd party black box code and stale data. No way to improve."

Fingers crossed.....

Ooooh. Two great updates in as many weeks.

It better be as good as Waze, is all I'm saying. :)

How exciting....

It was the 10miles of single track country lanes (with passing places) that it sent me on recently that really lifted the excitement level for me personally.

Lets see.

Did you pass anyone?

Just off out to make sure my car is on Wifi, see if there is any chance of speeding this up!

Just noticed that 2018.10.2 is out which is the new browser.

Go figure that it was released after 2018.10.4. :)

2018.10.4 is causing widespread crashing of the head unit, they've pushed a reversion out. Found that out when taking the X for its extended stay at the menders.

It’s been a while now, but good to see that 3.5years after my first post, the satnav is still capable of this kind of craziness.

132808




Not just the mad routing, but the idea that we might be able to manage the 14mile diversion in just 2 minutes. Along single track roads....

And don’t mention the waypoint navigation we’ve been promised for the last 3 years.

Good luck to anyone with FSD 😂
