Well if the battery was the actual part that started on fire. I'd say it burned out of the pack. So then it be open(burned out) and then foam would have suppressed the battery fire. Unless you know that the pack container is made out of and may be surrounded by a strong thick metal that is fire resistant. Then you may have a point that the battery was not compromised. But I doubt that tesla would have spent such money or added that weight to the battery pack.

I've never heard of the battery burning out of the pack before. What sometimes happens is the fire department gets the fire to a point that it appears to be out only to reignite later. (hours) So the pack has been designed to contain the fire, and the big problem if there is an internal problem is getting everything inside cooled enough that it doesn't reignite. (One fire department went as far as filling a large dumpster with water and using a lift to submerge the car completely in water to prevent reignition.)

The pack has channels designed to vent down and to the sides in the case of fire. Since the cells contain O2 using foam to deprive them of oxygen doesn't work, (LiNiCoAlO2).

submerging the pack or parts of it in water seems the only sure and safe way of extinguishing an EV battery fire

Update on the status of the class action suit: To no surprise it has been delayed yet again because of COVID-19: CAND-ECF-Confirm Request
The mediation planned for 5/27 has been reschedule to 6/25. So expect the next update on the case at the end of June.

Turns out supercharger status on the maps with no VPN is missing so slight bummer. Supercharging still works fine on v8.
Also discovered that if I charge with range mode on I get my original charge taper I had when it was new. I never realized until now that charging with range mode off was slightly slowing me down.

Not clear to me how to read your 2nd paragraph. How do you experience faster (higher average rate / less taper) supercharging? With range mode ON, or OFF?
With range mode on, I charge at 74KW at 54%. With range mode off, I charge at 68KW at 54%.
That's interesting. Why does range mode change the charge curve?
Range mode doesnt use energy to heat the battery.
Maybe your vehicle is having trouble keeping it cool.
A trick I saw was to remove the surround in the frunk. It gives the radiators more airflow
Just the opposite. With range mode on you use less energy to both heat the battery when it's too cold and cool the battery when it's too hot. This has been discussed and proven many times. Turn range mode off you want your battery temperature to be more tightly controlled by the BSM.
I just don't know why it didn't occur to me that this would effect charge rate as after the fact of realization it's obvious as to why this is the case. With range mode off, the battery is allowed to heat up to 114 to 117F vs 109 to 110 with range mode off (same SOC charge ranges and temperatures) which I've just verified with my 4th supercharging session today.
Turn on range mode reduces the aggressiveness of the BSM to controlling the battery temperature. This is why if you drive with range mode on in hot weather, your battery will get much warmer than if you drive with range mode off but then you'll use more energy to keep the battery cool.

Also noticed that, but to be honest, I was becoming disenchanted with the real-time status display. I found that many times it would show 2 or more stalls free, but then when I arrived at the SC, it would turn out those two stalls weren't functioning, or they had already filled up and a line had formed. A display like Google's "popular times" which shows usage trends and busy periods over a typical day would actually be more helpful to be able to plan departure times.

This is correct mostly, however, once plugged in, Range Mode On or Off for thermal management makes no difference. While plugged in and charging, the car does what it wants. Range mode only affects the vehicle when not plugged in.

Want to report, on Firmware 8.1 on my MS90D, Voice commands magically started working again after a month. This happened Tuesday. Still no app access.
My MS still will charge from 0-100% in less than 2 hrs.
My MX 75D, got another firmware 10.2 updates last week. 0-100% Takes 3-3 1/2 hrs on supercharger.
Not temperature dependant.

I always believed this to be true as well and still believe it is true for AC charging. But my suspicion, based on my 4 supercharging sessions yesterday with range mode on and off is that when you have range mode on, the BSM is being more lax on battery temp control by prioritizing how much range you get in the same period of time charging with range mode on vs off.
Keep in my I'm on V8 and this is probably not even remotely true with the current software given how they've basically cut supercharging speed in half on older 85s.

This is something I am willing to try on v10. I will let you know if it brings me any improvement.
****en bullshit! I want to know what is going on. If tesla is back producing cars they should be answering to this lawsuit. F U ELON!
Well it was a joint decision to delay the mediation. If the plaintiff didn't want to wait they could have refused the extension. And in fact, they can still cancel the delay at any time. They must think that they will get some benefit out of the mediation vs. going full steam ahead on the law suit.
