My experience with this (late 2017 Model X HW2.5, Netherlands):
Disclaimer: I washed the car, took extra care to ensure clean sensors and camera's.
Additional Lane Detection Broken
In way, way way to many cases, the car seems to not detect the lanes left and right of you.I first tested the firmware at night, and blamed that (even though I was on the brightly lit beautifully marked 5 lane A2 south from Amsterdam), but experiences over the weekend in both cloudy and bright weather tell a different story. It happens all the time.
No more lane detection/display on non-freeways
Previously, the car would detect and display additional lanes also on multi-lane highways (80/100 km national roads in NL) - So far, I haven't seen it do that anymore.
Autosteer
Which brings me to autosteer. Because of the previously mentioned change, I can no longer manually ask Autosteer to change lanes/overtake on non-freeways.
Regarding the steering angle limitation: I haven't noticed a limitation yet. It could be that it takes some corners a bit slower than before (and still does like a student driver that focuses too much on the road 5 m in front of the car, instead of looking 30+ meters ahead for a more fluent experience).
An example:
This curve-with-intersection (going west->north) was navigated on autosteer with an 'appropriate' speed (for my mom
), which means a serious steering input by the car.
NoA available but mostly useless
NoA is available on all freeway routes I've tried since thursday.
* It does suggest takeing over (for speed) - IF it detects a lane to the left (50%)
* It does properly suggest lane changes for navigation - unless it doesn't see the right/left lane...
* It does NOT actually go left if there's a car coming up from behind (no matter how slow or far)
* It often cancels for timeout (because it's chicken *sugar* and doesn't dare to go left)
* It often cancels (even violently midway through) apparently because it no longer sees the lane (my theory)
* It hardly ever dares/manages to actually make the lane change (timeout, cars, lane 'lost')
* It once suggested going to the middle lane in order NOT to exit (even though the right lane is not going to be an exit lane) - could be a map issue
* If I'm on the right lane near my planned exit, it nicely exits the freeway (but once ON the exit lane, the display disturbingly shows that it's going to hard exit that lane to the right as well - but fortunately doesn't).
In short: doesn't help, feels dangerous and unpredictable to me, other drivers. Will NOT use for a second with passengers in the car. (I tried, and my wife kindly convinced me that should would drive the rest of the way).
Tonight, I'll return WITHOUT NoA to see if this update affected autosteer on the freeway in any way.
Other
* Rare cases of phantom breaking (no change)
* Gut feeling: more cases of phantom-slowing-down in refusal to pass a car in the right line.
