Can anyone top this ?
Yes - at the recent Milton Keynes clubhouse event, Georg Ell said it is top of the list - they get so many complaints about it. They just need to talk to Waze and licence it!Crazy! I see this type of thing quite a lot.
The tesla sat nav often routes me a much longer/illogical/more time consuming route compared to waze. Why is it so poor? Do tesla plan to address this anytime soon?

Agreed. Seems blindingly obvious to me that the issue is phantom road closures in the traffic data, but somehow despite this they haven't even managed to make an interim fix. Simply ignoring all road closures entirely would hugely improve things, since the false positives massively outweigh the real incidents.I think that the crazy stuff goes away if traffic rerouting is switched off: it seems like the Nav is seeing phantom roadblocks and trying to route around them. I've seen it calculate all manner of detours until I cross a particular section of road (at which there was no delay/issue) and then it corrects itself quite happily.
Oh. I wasn't aware of that. I'll mention that to him next time, assuming v8.1 doesn't fix it.He's said that at every single clubhouse event since they started holding them in early 2015.
A mixture of "Not Invented Here", and cost savings, would be a fairly educated guess. Google have the whip hand regarding pricing.I just don't see why they don't use Google maps or any of the other major routing providers. Surely a licence fee is better than all the hassle?!
Would CarPlay / Android Auto be able to integrate with Energy app though? Hopefully Tesla are looking for a solution that integrates traffic-based route planning with the Supercharger network and predicted energy usage, and to do that they need more than a dumb phone mirroring function. The current Nav can work offline as well which is important for areas of poor mobile data coverage (albeit another frustration as the large-screen map shows up-to-date Google maps and traffic roads while the console Nav uses an offline, less-up-to-date map plus different flakey/misinterpreted traffic data).Personally I think CarPlay / Android Auto would be more sensible. Not only would it offload the whole mess of sorting out nav, but also push the costs for data and streaming services onto the users, not Tesla.
Tesla have never used Google for routing (they use Google for the big screen map, and for address lookup into a physical location, but not for routing nor the turn-by-turn map that appears next to the speedo). The routing has always been implemented in the car, using an offline map database. Originally the routing was licensed from Navigon; now it is believed to be Tesla in-house. The actual map data might still be Navigon, not much about the map or updates has become public. Traffic data is from Inrix (or was last time I sniffed it, a while ago now).Has anyone compared the routes Google offers on a desktop against those calculated in a Tesla? Just wondering if Tesla empty any custom routing algorithm. I haven't used Google's mapping for route calc very often but crazy routing like this used to be quite common in the early days, not seen stuff like that for a while!
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.They presumably want to integrate with Autopilot rather than carrying two inconsistent offline map databases. Scope for hours of fun if autopilot and the navigation have different ideas about which roads actually exist in an approaching junction...
I, like many others, have a navigation app on my mobile phone to compare against the Tesla routing when doing longer journeys. I use the one built in with Google maps and have never seen the roadblock-avoiding detours offered up by the Tesla Nav (plus it includes several newer roads which have yet to make it onto the on-board Tesla maps). Waze is also a very popular with Tesla drivers. I don't think there is a particular problem with the basic routing algorithm (apart, perhaps, from occasionally using uncomfortably narrow roads), it's the way it tries to re-route in response to traffic conditions that is buggy. If traffic re-routing is off it's fine, if a little optimistic on journey times compared with Google.Has anyone compared the routes Google offers on a desktop against those calculated in a Tesla?

Not heard any rumours. My memory says there were some releases thought to be 'tweaked Navigon', and then a release with distinctly different behaviour that was the switch to pure Tesla. It's possible of course that they had a source licence and the 'Tesla' version was merely had more pieces replaced.
