Hm, thanks for the details. I was of the opinion that what we had asked for (and who knows what we got!) was an audible indicator with the red lines were visible. I thought they were only 'there' when you started to change lanes. I thought that only happened when the turn signal was on... so, that is when you would hear any beeps, only with the turn signal and the red 'obstruction' lines.In Switzerland I tried 4.2 and 4.3 every which way, in AP, TACC and manual driving, with indicator into car in next lane and it never made a peep, although the line on IC and the icon of car in BS both turned red.
Only thing I did not try is *not* indicating while steering into the lane of another car a bit ... will have to detect a suspect who looks to have slightly strong nerves for this test
PS: Just tried it without indicators in TACC and manual ... no BSW at all, visual or audible, so I don't know what they are doing differently up in Norway, unless it is someone with a M3 and early access software?
A further note regarding the AP indicator memory function on MS: on 2-lane country roads it will overtake if clear of opposing traffic for 200m up ahead but cancel the signal and move back to own lane if seeing approaching vehicles, or just immediately cancel the signal without moving out if opposing vehicles are very close or if seeing a solid white centre-line. Another nice surprise!
Detection of bicycles seems improved but still does not deviate around them. For crossing traffic appears to brake a little less suddenly. Visualisation of passing cars in IC is definitely smoother.
I have the feeling with WA-cam now more active AP should pretty well stop for a pedestrian moving on zebra-crossing in town.
On my standard countryside test-stretch today 4.3 performed steering and braking much like 4.2 but corrected itself to the wrong side of the road on the 110° bend at 30kph and again on another spot with no centre-line. i.e. the steering is "seeking" more actively and makes pretty sharp corrections which sometimes go the wrong way. But for normal curves and markings on stretches with 80kph limit it is no longer the hair-raising experience of scraping around most corners far too fast.
Finally, I think AP is now watching for blinkers on other vehicles or at least accurately predicting their paths, as I have today caught 4.3 giving way on two occasions before the other car was within 0.5m of reaching the lane line between us, once on a merging motorway slip-road and also in ordinary motorway traffic cutting in from the right. Another goodly omen for NoAP, methinks.
In summary, I have been surprised [in the good way] to discover 2019.4.3 contains much more than I was expecting!
I could be 100% wrong, and I guess the documentation for 2019.4.x/5.x doesn't help as to what we really got. Or it's just broken because Tesla doesn't/can't/lets us test everything.
If we ever get either of these on our cars, I'll test myself....
