Looks like Model Y heat pumps are seizing en-masse in Russia as well. This is how it looks like:

(in the video they just count start attempts), video credit to some Russian Tesla owners group

When you take the compressor apart you see this

I tried to find a teradown of a working unit, but only can see the outsides of it by Munro. Anybody can link me to the inside views?

In case you cannot tell, these parts are NOT normal, it's the sign of some metal parts hard-rubbing against each other creating this sort of a wear pattern

To me this does not look particularly fixable via OTA.

This might also be fallout from the bad sensors workaround earlier

Got a pretty worrying #TeslaCrashFootage in the mail.

This is on AP (NoA, really), 75 mph into a truck, no braking, no warnings of any kind.

The firmware is 2021.4.18.2, accident in June 2021.

radar-equipped car (but hw2.5 of course)

the truck was seen by both the radar and also could be clearly observed by the narrow camera from quite a distance away (pictures are spaced 1 second apart)

In fact it was when I reviewed the narrow cam video footage I saw there's a guy with a flashlight behind the truck (I hope they were not hurt and ran away as fast as they could after seeing Tesla not braking)

USB drive was recovered from this car showing the fire started in the house before jumping to Tesla just as was mostly evident from the outside video

Interesting that (I presume) the owner was in the car and saw everything, escaping out (the car was plugged so cannot even drive it until unplugging.

the drive location in the glove box likely saved it even though it appears to be damaged some

@rice_fry

Holiday weekends are great for some fun are not they?

Worked with @rice_fry on the Tesla depth perception NN.

Remember that stuff in ?

Well, the cars actually have a depth perceiving net inside indeed. though unlike what's shown it's a lot lower res

A whopping 160x120 grid (so 1/8th of the native camera resolution) but hey those are actual 3D points in space. I don't know how to make a 3D video, so just visualizing "distance" as "brighter = closer" on the scale of 5 to 62 meters (the actual limit of the output):

Here's the corresponding time-synced video to better understand what you are looking at.

Pretty cool actually despite all the limitations.

So in regards to the recent Chinese crash with video where AP exits roadway in sharp turns:
I long planned to do a demo of a similar condition but always forgot and I guess better late than never.
It's actually really easy to reproduce
m.weibo.cn/status/4655186…

Find an (empty!) road with a sharp curve and point autopilot at it. For most safety ensure there's an extra space outside the curve so you can catch the car before it crashes into stuff and boom!
(this is 2021.4.18.3 btw)

Remember to always pay attention when on AP!

If you enable debug mode you see the car actually outputs various alerts before the eventual "take over we are giving up" (weird there was no diseng chime btw)
and it knows it cannot take the turn safely at those speeds, in fact it tries to lower speed but definitely not enough

Some more fun with radar-less Model Y (thanks @spleck)

First we laced a brown box with foil (for great radar response) and tested my model X on it (FW 2021.4.18)

It rammed it like nothing, but we did get an FCW.
