You're probably looking at the older version of the HPWC. For some reason both old and new HPWC manuals are listed, at least in my MyTesla account even though I only purchased one HPWC (the current version)
The manual for the current HPWC is here: Wall Connector with Side Dock Install Guide
My wall unit worked once. Professionally installed. 100 amp service. Just get a RD light at charge port. No lights on wall unit. Tried breaker reset and unit reset. Button on supplied cord does open charge port lid. Slow, backup cord works. Have P100D and high amp car upgrade. Disappointing.

There's no reason to run the data cable back to the panel. There is also no reason to run it in conduit. Just run it between the two HPWCs, stapled to the wall/ceiling.... This seems to mean that you need to run another conduit overhead between the two HPWCs for the data cable for any large garage.
Does that all sound correct? Does it make sense that the data cable/signal wouldn't reach all the way around a standard two car garage? Seems like a strange limitation for this function of multiple HPWCs, unless I'm missing something stupid (wouldn't be the first time...). ...
The problem with moving the subpanel 'closer' is that then unless you route the main power conduit over the ceiling to the other HPWC, it's then longer to the other HPWC., since you are going to the furthest ends of the garage, with the main panel in one of the inside corners. That may be doable; another wrinkle is the high ceiling, since the garage is under the master bedroom.There's no reason to run the data cable back to the panel. There is also no reason to run it in conduit. Just run it between the two HPWCs, stapled to the wall/ceiling.
For that matter, I would position the subpanel closer to one of the HPWCs so that I didn't have to run two circuits (three with the 14-50?) all the way from the back corner.
The data cable is low-voltage, so there's no reason it needs to be in conduit that I can see. Certainly some of the install pictures on here have shown it not in conduit. As far as the panel positioning, I would calculate the total overall length of the wire runs, plus the aesthetics of the install. From your verbal description, it sounded like moving the panel would save a lot of wire, but I could be wrong.The problem with moving the subpanel 'closer' is that then unless you route the main power conduit over the ceiling to the other HPWC, it's then longer to the other HPWC., since you are going to the furthest ends of the garage, with the main panel in one of the inside corners.

As for the data cable, if the manual controls, it says this:
The wire used for this local network must share the main power cable conduit or be housed in a separate conduit.
That's how I got to where I got. Use the power conduit (too long) or another (what a pain...).
I think we're down to the usual 'do the local inspectors treat the manual as gospel or not' sort of thing. In any case, I like your idea of moving the subpanel close(r) to the first HPWC. Then, larger conduit from it to the second HPWC (over the ceiling) is shorter than my original plan of going horizontally around the room and also would be short enough to include the data cable. It also has the advantage of fewer 90 degree bends, which is always nice.The data cable is low-voltage, so there's no reason it needs to be in conduit that I can see.

I installed my mid-Nov. '16 with 100 amp service. From the charger manual (and confirmed on my first charge), '16 90D, all I could do was charge at 48amps due to the onboard charger limit. The onboard charger limit is just that unless you have the optional dual charger. Understand that the Supercharger over rides the home charger (onboard) limit and pushes 70+ amps.Ha. It so could have happened that way.
The Superchargers are capable of supplying ~360A...I installed my mid-Nov. '16 with 100 amp service.

My charging setup
Eaton 100 amp two pole breaker
Hubbell ‑ HBLDS10 ‑ Disconnect Switch
Ekm Metering Omnimeter pulse v.4 w/ ekm push
Tesla HPWC at 80 amps
Ran awg 3 for the two line and awg 4 for the ground
In case something goes wrong and or a requirementI like the idea of a disconnect switch, But when/why do you use it?
Nearby disconnect is required if over 60A in many jurisdictions. One reason is for service, so the person working on the equipment can confirm that no one walks up and turns it back in.I like the idea of a disconnect switch, But when/why do you use it?
