Phantom Braking

[idoco]

AP1 is still better at minimizing phantom braking compared to AP2+ versions.

^^ This

Driving a loaner with AP2 yesterday. Had phantom braking three times in a forty minute drive! With my AP1 MX I might get phantom braking once a year.

This was a clear day, on well marked roads with limited traffic. In all cases it appeared to be triggered by shadows on the road.

I was planning on upgrading my MX when FSD is fully implemented. But between loosing free supercharging and this unacceptable braking I may be waiting a lot longer.

P.S. I will say that the steering on AP2 is much more solid than AP1 in borderline situations.

maybe it picks up the speed limit. watch the GPS speed limit in the display

So I thought this was a great point... I have 2 places I know that for some reason the speed limit in the Tesla goes from 50mph to 35mph and back to 50mph over less than a quarter mile- even with the new speed limit sign reading (which is not what the real speed limit does- it just stays 50mph)... its just something in the map that's incorrect (but not incorrect in WAZE). I just know when I'm driving in those spots to never use autopilot.

Hopefully this is true once it gets rolled out to every autopilot user regardless of if they have FSD or not.

The worst thing about this IMO is that I cannot even use "regular old cruise control" without stressing about this.

Sadly this is true, I'm disappointed that I can't even use cruise control on the highway now because of the phantom braking fear (and yes it has happened to me many times on clear straight roads). I don't blame the technology I blame Tesla, I've had other cars that have used radar systems and they never phantom braked, ever!
I've looked and I can't see that adaptive cruise can be disabled, that would cure it because after 8 years they are probably never going to make it work right 'with a software update'.

FWIW:

I have MS AP3.0 with 35k miles on it and another MS with AP1.0 (Mobileye) with 140k+ miles on it.

I experience Phantom Braking from time to time with AP3 but have NEVER experienced it with Mobileye.
