I don't need to know that badly.
Ah, ok. Sorry to learn of that limitation.
I'm quite certain it's reading the signs. It misses one near us that is obscured by a tree and reads one that says the limit is 25 except where marked even though that sign is in a 35 zone.
Press the accelerator with your foot. AP2 will still steer, and you can go any speed you like (up to 90mph).
Eh, if I have to pick between steering or operating the pedals for 20 miles, I will just steer. There is light traffic on the road, so having TACC adjust the speed automatically is more valuable to me than not steering.
In my 6/2015 AP1 MS, it reads the street signs with extreme accuracy. Even temporary construction speed limit signs and such.
The biggest annoyance is school zone signs. It doesn't read the TIMES for the school zone speed. Just tends to assume the lower speed is 'now'.
I was over in Canada over the weekend and was REALLY amazed that the car read the KPH signs, and AUTOMATICALLY translated them into MPH on the IC!!! Now THAT is cool!
It reads them for me too well. A cpulpc of cross traffic signs are bent and the camera picks it up and drastically slows down, and I have a 50mph that has a tree branch across it and it reads as 80mph
After a 240mi trip, I see that the speeds on the freeway are pretty accurate but on other highways it can be pretty bad. Coming into a small town from a 55mph road the speed did not change even after the second huge 40mph sign. Some time after that it dropped to 40. When it does change it often fades out and then a few seconds later it fades back in. I think that (fading) may have happened at the same time the speed reading was replaced with the gps data.
And btw, zero nags. Haven’t seen one in almost two years. I drive (on AP) with my right hand partly resting on my knee and partly imparting a torque on the wheel. My left hand is resting on my left knee an inch from the wheel.
Just checked, it appears it still reads speed signs just fine, though it totally missed one which was surrounded, but not at all covered, by branches with lots of moving leafs.
My 2016 AP1 reads speed signs. It does NOT read stop signs. It does on occasion read a route sign (OH25, OH65) as speed signs. OH65 isn't a problem but the posted speed on OH25 is 60 and the AP immediacy slows when it misreads the route as a speed sign.
My 2015 AP1 reads speed signs all the time, I am surprised how well it does work, some can be really small in construction zones and it updates the display right as I am passing the sign.
Thanks for the reports, folks. Looks like my car Is an outlier.
I was hoping for more reports from facelift 2016’s, perhaps June or later. Perhaps being closer to the AP2 release has something to do with it.
The September 2016 service loaner I currently appears to be reading speed limit signs on every chance I pay attention to watching the speed limits change.
I don't think the car reads anything. The car has access to a database of speed limit sign locations and changes accordingly.
I find that annoying because it won't go that limit in AP (or 10kmh over if that's what you have it set to) until it passes one. It knows by rights that the limit is '80 kmh' (50 mph) but it stubbornly goes max 70 kmh until it passes an 80 sign where it will then go up to 90 in AP.
I think it does read, or at least mine does. There is an on-ramp to our ring-road highway that I take every day on my way home from work. The highway is 100 km/h, the on-ramp is 70, and it comes off a surface road that is 50. Nearly always the car displays the correct 100km/h speed limit once I merge onto the highway, but every now and then it thinks the limit is 80. If it was getting values from a database, that database is being updated really frequently (like daily) and occasionally updated with incorrect information. Not to say that couldn't happen, but it sure seems more like it's reading the sign and occasionally misinterprets due to glare, shadows, or other vehicles rather than pulling from a database.
its most certainly does, it changes almost every time I pass the speed limit sign...even temporary ones.
My Feb 2015 AP1 S85D reads speed signs reliably. It will update the screen (and the car speed if using AP) quickly after passing the sign. Pretty reliable. School zones outside of school hours are confusing.
The only error I've noticed is I once passed a speed limit sign which was knocked sideways and it ended up reading 5 mph instead of 35.
If it was truly just a database read, then the database AP2.0 uses is different than the one AP1 uses, as AP1 is significantly more accurate from my experience owning AP2.0 and having service loaners with AP1.
My 2016 AP1 has never read a stop sign. You sure that's a thing?
