I noticed the same improvement today with auto max speed.
I have noticed no changes to ASSO behavior. None at all.
As in manual mode doesn't keep up? Yeah, the specific examples I mentioned were cases where maximum +30% manual offset would have been have been insufficient: 25mph -> 32mph and 30 -> 39, so AUTO's higher +50% offset allows it to go the appropriate speeds that others are going.
Ha, I guess I wasn't reading very carefully. Sure, that's going to be an issue and a "difference" which has been made clear, but I would say those situations are probably outliers (apparently not for you). In addition the manual mode allows adjustment, which is crucial. (Also, wouldn't 39mph in a 30mph in manual mode really not be all that bad even with the current setup?).
Along those lines, there's also still an advantage to manual mode, in exactly these misdetection scenarios described above - it happened to me today.
The vehicle detected a 35 mph limit on Mira Mesa in a 50mph zone. Everyone was going 55-60mph. I was in ASSO mode. So I accelerated to 57mph not knowing what was happening, and was immediately met with strong slowdown. ASSO hidden limit of course was 52mph. Looking down, I saw the issue of the 35mph, so switched to manual mode and dialed up. Problem solved (no other way to solve it but to disengage or keep accelerator pressed!).
In the end, with the exception of the set speed offset which is well known, and wherever that has an impact, these modes appear to be identical in their behavior, and still haven't heard an example otherwise.
So manual mode remains a solution with minimal downside who want the vehicle to speed less. You get all the benefits of ASSO mode on city streets.
Today in ASSO mode I saw 52mph in a 50mph, 47mph in a 45mph. A few instances of 47mph in a 50mph. So generally far too slow. And of course there is no way to fix this with manual mode. So this remains a major issue.
I don't really see a solution here except to have different offsets for different types of detected streets, and then have the vehicle actually try to honor the user's preferences. It's nice that the vehicle now doesn't go inappropriately fast in most cases, but it's just so complicated when there are multiple moving pieces - car doesn't detect the right speed, user wants a different speed, conditions dictate another speed, etc.
All I know is overall I'm less happy with it than v11. There are places where it is better (namely by not speeding along inappropriately to try to get to my set speed offset of 16% or whatever on residential or slow streets), but surely there are other solutions to that which don't mean sacrificing the general desire to get to your set speed offset in most other situations.
Chill should be about 5% which is fine for me.
This is only on the freeways.
When I cancelled Auto, it showed a computed max speed of 52.
No it's not a bug. The set speed is 50% over the limit in ASSO mode. (The excessive speed in a detected 35mph zone might be a bug, but that excessive speed is not related to the set speed offset in anyway except that the 52mph limit acts as a cap, keeping the speed DOWN - but this limit
does not contribute to the tendency for the vehicle to proceed to that limit speed.) That set speed offset limit is the only difference between it and manual mode, to my knowledge, which you took advantage of by switching to manual mode. (Other than the freeway differences, but that's a different topic 5%/10%/15% determined by driving mode.)
Exactly what I saw tonight, unfortunately I was in a
50mph zone detected as 35mph, so I also had to cancel ASSO, go to manual, and dial up to 60mph. Then I could just kick up the speed to keep up with traffic and wait for the decay without it jamming on the regen to get back to 52mph.
The set speed offset limit is a hard limit and if the car is going over that limit, even with user input, as soon as the input is removed, it will rapidly bring it back (the problem I was having in ASSO mode). However, when the vehicle speed is under the ASSO- or manual-set-speed-offset-determined limit, you can kick it up, and even if its steady state would tend to be slower, it will tend to respect that user input for a "good while."
All super clear and simple. All the new users will be thrilled.
