    This morning the Nav on Autopilot threw a message, I forgot to turn on the cam so couldn't capture the message exactly. But it said something like: "The car is going to maneuver, need manual assistance" in the middle of the freeway because I missed an intersection ramp. That freaked me out!

    Not yet. In three months maybe, six months definitely.

    This is welcome news, but at what speed? The answer should be relevant to the rather pained question of whether AP travelling at up to 90mph on the Highway can avoid smashing into stationary firetrucks (or other traffic jam) after a leading vehicle moves aside.

    I'm eagerly waiting to see a dashcam video [with the IC blended in] of AP2.5 on v9 stopping smoothly in that situation, then continuing on seamlessly when the obstruction clears. If ever this legacy & potentially fatal weakness of AP is comprehensively eliminated, and demonstrated as such, then shall I venture to believe that FSD is even remotely possible given the current sensor suite.

    However, this is probably not yet the case, as otherwise Tesla would surely have loudly changed the Owner's Manual at the spot where it defines Firetruck Super-Destruction mode:
    Traffic-Aware Cruise Control cannot detect all objects and may not brake/decelerate for stationary vehicles, especially in situations when you are driving over 50 mph (80 km/h) and a vehicle you are following moves out of your driving path and a stationary vehicle or object is in front of you instead.

    ... so anyone testing this in order to capture the happy video should do so with great care ...

    Never remove a warning. Otherwise you are more on the hook when the 0.00001% event happens.
    (Note: FSD of course will not get to have such warnings)

    @verygreen can you use this same procedure to downgrade back to V8 after being updated to V9 provided you have the V8 firmware file?

    Even if this "works" I would be extremely hesitant about doing it. To be safe, I would assume that Tesla does not thoroughly test or plan for downgrading and so you risk bricking your car by doing this.

    Anyone else see a bunch of large downloads recently? As far as I can tell they aren't firmware downloads unless Tesla switched to downloading them over VPN. Currently on 39.6.

    it may or might not work depending on how old your v8.1 is. There's an internal versioning system and hopping between versions that have the same internal version should be ok. I never tried it myself, but 18.39.x to 18.36.2 should work, I think.

    That's about the size of the v9 download that we saw on cars which already had a 36.x version. Looks like yours keeps having issues and downloading it multiple times.

    Otherwise, it could be the 5 GB maps download but my router showed that as one big download, not a bunch of smaller ones.

    There are two threads dedicated to this found bug/feature. Its also discussed in about 5 -10 other threads discussing v9 in general.

    Got the new software 3 days ago but only drove the car the next 2 days. Drove the car and then parked it. When I came out of the business, the car seemed dead but the handles presented themselves. Center display black, seats didn't move, a/c out, nothing worked. Tried to reboot but the screen remained black. Did this 3 times and slowly things started coming back on. Took about 5 minutes before everything came back on. Scary. The next day I had the same thing happen at my house.

    Any ideas what happened? Car powered off? Any special way to get it powered back up?

    I've seen an 8.1GB download to my car two days ago. It's an AP2 MS running .34.1 in Germany. No update notification or map hint since.

    I've previously experienced an unresponsive car with dark MCU and solved it by keeping the steering wheel dials depressed for about maybe 20s.
    It will then come up as usual after a reboot.
