Bad news Sunday. If you had infotainment computer in your Tesla replaced (model3 FSD upgrade, mcu2 retrofit, mcu1 emmc fix or any other fixe requiring computer swap) - consider all accounts you logged into from the car compromised and change pwds.

In particular if you log into spotify - the password is stored in plain text. gmail and netflix are stored as a cookie but still give a potential attacker access.
The of course all recent calendar events and your phone book and calls history too.
Particularly annoying since I hoped they'd start encryption of the data after that CNBC report from the last year, but nope. It will come for sure this time though I guess.

Other than this I welcome Tesla's contribution to lowering prices on these computers on secondary market.

I got some flack last time for how my typical highway speeds are wrong to measure Tesla energy consumption.
So I decided to do a bit of a cosplay of the "typical slow Tesla". I set TACC to 75mph (all around reasonable hwy speed I hope).
Car is my new Tesla X LR+
No level ground here so did a 70 miles trip 35 miles each way, taking measurements along the way. In the telemetry picture you can see the speed was constant at 75 except where I turned around.
Elevation change 276m->316m->212m->312m->276m so should be all valid
On the first leg of the trip going downhill and dropping 70m of altitude I recorded 331Wh/mi at 75mph.

As I have a bit of DM explosion lately about possibility of various major changes coming out of Tesla soon, here's the general take for everybody interested to consult:
TLDR, something major is brewing ,but I don't know when.

1. back in 2019 they suddenly froze their releases
on 2019.40 branch and only backported essential stuff there - presumably to prevent leakage. Meanwhile updates slowed to a crawl. Eventually 2020.4 was released over a month from previous release and already leaked some info.
now it starts to look like they'll freeze on 2020.4
as is evidenced by 2020.4.10 getting out with some very limited changes (remains to be seen if this is going to be a trend).
We have seen a similar trend play out in early 2019 where 19.4 was released in late Jan and 19.8 was released in March as preparations for hw3 launch were

so I did a first testdrive of MCU2 retrofit.

I must tell you that IC2 is way-way more responsive and lag free compared to IC1 so whoever was telling me IC2 is equally laggy, you have not been using IC1 for a wile I guess.

I can also confirm hw3 backup cam view is jerky somehow.
I cannot imagine why anybody would opt to NOT do the mcu2 retrofit after this experience (current component pricing around ~$1600 from junkyards).
You only need: MCU2, IC2 and the new tuner (can skip that even, e.g. I don't have it yet, but then updates are complicated).
No harness changes needed which is a definite plus (was expected).
