Out of curiosity, does anyone know if both rear wheels have the e-brake style caliper or just one side? I would guess both in the event that you break a half shaft, you'd lose Park functionality, but who knows.

Has to be both because when I put my wheels back on I can torque the rears without pulling my hair out. Wish I could simultaneously Hold the fronts.

I'm glad no one is injured.
Also understand why would anyone hesitate to upload their dashcam. But in this scenario, even though it would most certainly not benefit you, it would be good for others to learn how bad the instant failure was. Especially those who text on their phone thinking their tesla can handle it, have to see this. This is just my opinion, just for your consideration.
In my experience testing from 5 mph it was not slow or little braking, it was violent. It's the same brake used for hill hold.Here's a video of how to actuate the e-brake while driving for those wondering:
You can see from just a random picture on Ebay of a Model 3 rear caliper there is a black part that is the servo motor that that parking brake actuates. This motor is electrically driven so it'll still work even if you lost all your brake fluid. Obviously due to it being only on the rear brakes and due to how the motor works, it's very slow, so the braking force is very little compared to normal brakes, but it's still better than nothing.

I guess it depends on if talking about the Model S (which uses a screw drive which is likely even slower) or 3 (which uses a servo). However, I get the impression it's still slower than the hydraulics. It may be more harsh since it bypasses all the other brake systems (like ABS), but the braking force is definitely much less than regular brakes. You can see that from the video when the car is going at higher speeds.
Here is what they said. I will update more when they respond.

Make sure they answer your question in detail.
If the failure was from an outside force (debris), they would have said it and would be sending you an invoice to approve before work is to proceed.
I’d demand pictures of the failure! Or if the SC is close to you, go over there and ask to see it.
Lol there's no way your wife is getting back in the car if Tesla just says "yo man we swapped out your brake lines... have a nice day!"

If brakes are set up in an X pattern with RF & LR on one circuit and LF & RR on the other, loosing both front hoses would cause complete failure. Hard to think how that could happen. Does anyone want you dead?

Just got off work, they never responded to my questions after what they said at 11 am. I’m going to pay them a visit tomorrow and try to take pictures if I can.

Wow, Tesla doesn't offer an extended service agreement? So it's just 4 years 50k? That's interesting.

4k/50 bumper to bumper, 8 yr/100-120 (depending on model) for powertrain/battery
Xcare offers a 3rd party extended warranty if someone wants one that's pretty competitively priced (they offer it for S/X too as an alternative to Teslas)
Pricing here:
