Having driven both, I used to say (and have said here) that AP1 was more confident and felt more in control. That has changed with software updates and now AP3 w/FSD (can't speak for AP2 as I never used it) is much improved and has in my opinion far surpassed AP1.
If the OP is using AP2 w/o FSD, I would say that AP1 would probably be a little more sure-footed. I think meaningful development of AP2 stopped pretty much as soon as AP2.5 became available.
He did say it automatically changes lanes which AP2 does in Navigate on Autopilot(without touching the turn signal), so it’s a little confusing.But the ping-ponging OP is referring to, is long gone in AP2. AP2 is just as solid on lane keeping and in fact does a good job in faint lane lines too, which AP1 constantly struggles. I think in every metric AP2 has surpassed AP1. And I say this after having driven both AP1 and AP2 extensively.
I suspect something is amiss in OP's hardware.
[I forgot about the fact that AP1 does lane changes.. its been 4 years]
it even auto lane changed (something mine doesn't do).
Yes, it does sound defective. My AP2 has been working pretty awesome for a couple years now.Is my AP just defective or whats going on with it?
It's strange how different our experiences are. I wonder what variables affect this.I agree. I recently got a P85D with AP1 and it's much smoother on Autopilot than my XP100D with AP2.5 and EAP. Using the turn signal for lane changes is more confident than EAP-based changes, no phantom braking, and better lane keeping lines. I was initially disappointed that my S was stuck on AP1 but after using it a while I love how rock solid it is on the highway. My use case for AP is primarily highway driving. I'm really not that interested in nerve-racking FSD software trying to understand and navigate through complex intersections where I have to be alert anyways and driver behavior will always be unpredictable.

The only thing I noticed with AP1 was that it had worse phantom braking issues than my AP2 car.
What I experienced was sudden braking when there was no reason to brake. Not like a slamming on the brakes to come to a complete sudden stop, but an abrupt reduction of speed. Maybe it would have come to a complete stop if I hadn't tapped the accelerator to counter the braking. I was driving through Lake Oswego at 32 miles an hour with TACC engaged, when it occurred. I remember thinking, oh so AP1 does this too. It actually hit the brakes harder than when my AP2 car phantom brakes. Which it doesn't do very often or aggressively.Define "phantom braking" because I've logged tens of thousands of miles w/AP1 engaged (I use it everywhere... city and highway all over the country on all of road trips) on many different AP1 cars. Never once have I personally witnessed an AP1 car w/Autopilot engaged phantom brake. I've also never read of it from others on this or other forums other than this post outside of like two instances total and I suspect the variables including the operator in these super rare occurrences. Ether you experienced something remarkably rare (and not something I would use to gauge the two versions against each other) or we share a different definition of what "phantom braking" means.
I had a 2016 S 75D w/ AP2 until Oct 2019 (original owner), and it never had the AP problems you described. I suggest scheduling a service appointment to have your cameras checked. I had EAP which included auto lane change (manual signal and NOA).Yes my 2016 is AP2 w/o FSD. The loaner's AP1 feels far more confident and I would actually use Autopilot with AP1. AP2 scares me a little because it rides on top of the yellow line so I dont tend to use it. Ive already tried recalibrating the cameras but it doesnt help - my AP2 wants to hit other cars with my side view mirror because I guess Tesla feels that's normal behavior......
I have AP1 and mine does both lane changes and auto lane changes.
