Auto lane change, when not on a motorway, is a bit of a mystery. Sometimes it works, sometimes it doesn't, sometimes it doesn't due to user error. Unfortunately, where it decides to work seems to change from release to release.
I agree it is odd, there are many dual lane roads near me (mainly in towns) , where auto lane change never works. On some major A roads and all motorways I've used it is fine.
I keep hoping that some of this is a mapping issue that it will get updated, but as we know, Tesla maps have not been updated for well over a year now....having said that, I think I remember reading somewhere that auto lane change in UK is prohibited on any roads that allow bicycles.... or maybe I was imagining it?
Other NOA issues for me:
- the need to tug the wheel to confirm in control before a change is activated (sometimes I'm too heavy handed and it disengages)
- the UNECE delay between indicating and lane change is very annoying, sometimes I don't use it as know the delay will cause an abort.
- because of the UNECE delay, you don't know whether it knows you are in control and will activate lane change, so I sometimes continually nudge the wheel (some light indicator or "ping" would be welcome here).
- On a three lane stretch, lane changes whilst overtaking lorries in the slow lane also cause confusion and refused/aborted changes - it confuses which lane the lorry is in and freaks out, always.
hoping some of the Driving on city streets code will filter in the background to UK/EU to resolve some of this, and that UNECE will meet more regularly and actually allow innovation.
Pleased I have it though - I just love this kind of thing!
