Hello, rear radar :-)

Yes. BT could be used to assemble a mesh piconet / scatternet. Vehicles can elect to be master/slave nodes in the network and extend that network to other vehicles by being a master on those other networks. It's a whole thing BT can do. But you'd probably want a module in the nose of the vehicle as well if you were going to attempt to use it for vehicle-to-vehicle comms.
Platooning is just TACC. There's nothing special needed for that.

Yes and no on the platooning. Because platooning also means following closely, you will want vehicle to vehicle comms. Essentially they would be just tacc but the front vehicle could alert of issues so all vehicles could slow at the same exact time.

If platooning, the LED brake light activation/ propagation time would be very short (camera frame time likely the limiting factor).
Relying on an ISM band radio communication mechanism for autonomous vehicle control in an emergency situation would be a massive and unforgivable mistake. BT is not a real-time technology, and attempting to use it for real-time communications with potential latencies so high is pointless. And because they're in the ISM band, all they have to do is drive by a neighborhood with lots of wifi APs and they system grinds to a halt. Let alone how simple it is to jam the signal to begin with. No. BT would not be used for controlling the platoon like that. It would be used for secondary system communication at best- battery status, system warnings, etc.
Using the radar system on the front of the vehicle would be significantly faster reacting to an emergency stop situation than attempting to relay a BT message from the leader to all followers. The lack of distributed systems communication mechanisms alone make it infinitely simpler.
Not to mention that these cars have Wifi(with Musk mentioning plans for using said WiFi to act as an LTE access point. Even if you did want to do this type of communication, why bother with the much lower bandwidth/range option? It’s not like you need to worry about draining the battery.
Maybe for the 3 but the parts catalog for the X indicates that there are at least provisions for corner and rear radars in the HW2.5 package...

That’s not hw2.5, but very old parts. The corner radar brackets for MX has actually been present in the catalog since day 1.
It’s like a plan that never came to fruition, just like the «one-eyed» AP1 camera for MX.
Tesla Model X delivered with dual front-facing camera housing hinting at Autopilot 2.0
MX was supposed to be more advanced than it became
Gotcha, the language used in the parts catalog made it seem like it was an HW2.5 thing since it has listings like "ASY, REAR, RADAR HW2.5, MX". Hopefully the wiring is there at least so that if it does need to be added it could be.
Yeah. Btw the «rear» wording on that part is confusing too, but if you check the drawing you see it’s referring to a «rear» bracket, actually
Yep, it does... there is a radar unit that is different from the front one thought that is also depicted and has a P/N.... not that it matters much if it's not there. Given the issues verygreen has shown with the rear camera it sure would be nice to have a longer range fallback than the ultrasonics....
AP2 and AP2.5 have different front radars
The former a Bosch Mid Range Radar (MRR), the latter being a Continental Advanced Radar Sensor (ARS)Ah that's right... Interesting that they don't differentiate between the two units in the catalog based on date of manufacture as they typically do when they swap other parts out.AP2 and AP2.5 have different front radars
