Autopilot restrictions gone

[Hota]

I just realized a few days ago that autopilot is no longer limited to 5 mph over the posted speed limit on non-divided highways.

I've been playing with it and there's no limit at what I can set it to regardless of road type.

Anyone else noticw this on their vehicles? I can't say for sure it was part of the latest firmware upgrade since I just noticed a week ago.

Mine prevented me today from doing that when it saw an inactive school zone speed limit sign...

I don't think mine ever had a limit. May build, got it in July.

What is the minimum speed to engage AP?

 

[rypalmer]

Mine was still limited tonight to 10km/h over the limit on a non divided road.

I can engage AP while stopped behind someone in traffic if you want. That's nice at lights.

When not behind a car, my AP won't engage until 18mph. Not sure why this is the number they picked?

I'm still limited on v. 2.32.23. What version are you on?

Yes, I've noticed a few odd numbers like that. But not so suspiciously the numbers always seem to be Americanized conversions from rational metric numbers.

@docherf, 18 miles converts to 30 kilometers. (The internal calculations of the car are in kilometers.)
So they picked a nice round number that happens to be a common speed limit in European suburbs and near schools.

I thought it might be a nice even kph number, but 18 mph = 29 kph, not a nice even 30.

depends which way you do the conversion, due to rounding.

going from miles to km: 18 mph = 28.97 kph
going from km to miles: 30 kph = 18.64 mph

If the car is allowing AP at 30kph, then it's going to appear as 18 mph or 19 mph on the speedometer, depending on how the car rounds the figure displayed.

Man, you guys are a bunch of nerds!

I think it is related to the algorithm for recognizing lane lines.

I don't know if you've noticed, but below that speed, mine is always in "follow the leader" mode (car ahead marked blue, the Tesla follows the other car wherever it goes) while above that speed it is usually following lane lines (lane marked blue on one or both sides, car ahead marked white,) though occasionally it loses the lines and reverts to following cars.

I was actually amused by this transition - a couple times I've been places where it had to bounce between the two modes - and the car in front was ~6" to the left of center in the lane. AP centered itself behind the car, then corrected to be centered in the lane, then back to centered on the car, etc.

 

[Todd Burch]

It switches at low speeds because following distance is lower and the camera doesn't have a good view of the lane markings (what with the big car in your face and all).

That's the version I'm on!

 

[CHG-ON]

I am still limited to 5 mph over on undivided roads on 2.32.23.

 

[Hota]

Okay, playing with it more today, I found an undivided road that limited my autopilot to 5 mph over. I guess many of the undivided roads aren't limited for some reason - even with one lane each direction.
