    Hmm... that pic with the charge screen has some interesting data on it:
    cr473i6u445z.jpg

    Given the average charge session rate of 169 miles/hr, and 21 miles gained, he's been charging for 7-8 minutes. By that point, I'd expect the average charge rate value would be dominated by the maximum power delivered over that time (somewhere in the neighborhood of 70kW), and no the initial ramp-up time (which only talks 20-30 seconds on my S).

    Yet an average mileage gain of 169 mi.hr if you have an average power delivery around 70kW implies the car assumes a power usage of ~418Wh/mi.

    That's obviously way too high. And given the pack SOC appears to be in the lower third, I'd not expect any significant tapering at that point.

    There must have been some reason for a slow ramp up...

    My late 2013 Model S has a dedicated rain sensor for the wipers. Your post implies that the current S/X do not have a dedicated rain sensor. I wasn't aware of that.

    Of course auto wipers will come for EAP cars. It's just proving to be a harder problem than Tesla orginally anticipated.

    If he's charging in California then I'd say that's the new "normal" rate
    I haven't been able to charge at more than 70kw for a while now.

    My point is the implication of the car needing 400+ wh/mi... that's way too high.

    The car is charging at 70 kW. That is excellent for a ~ 55 - 60 kWh battery. If it can hold that rate up to ~ 70% SoC I'll be elated.

    assuming the header photo is the same car as the interior photo (additional photos show same white color so it probably is) it is sharing a charge with the car beside it. That could be the reason.

    In the original report from the person who took the pictures, the photographer was charging on the same paired supercharger and was pulling in 110kw. So the M3 was limited by the paired vehicle

    Since you have no idea what the car was doing earlier, I would not pay any attention to that value.

    I don't see this as a bad sign.

    I just did a check of my AP2 car and it turns out it does have a similar sensor. I never noticed it in six months of ownership. I just went out and when I hold the camera at the right angle, I can see the sensor is there.

    You are dreaming if you think they will recall all AP2 cars and give them rain sensors. They will find some crappy way to give us some functionality even if its not good to say they gave us the option they promised.

    That sure is a glossy display…
    Reflection issues?

    If it makes you feel any better, the AP1 automatic wipers are nearly useless. Seriously I wish I didn't have them.

    Interesting point. It would seem to imply tint on the side windows.

    Good point. The initial rate must have significantly lower...

    If Tesla want to reach FSD on AP2, they're going need a way to auto-wipe the windshield.

    No, he said adjacent stall. We don't know if it was paired or not.

    Sorry about the glare, @BestRadar, but here's a picture of the sensor on my AP2 car. I guess no retrofit needed. :)

    You have the logic backwards. The reason auto wipers suck on AP2 is because, well, do you care how good the wipers are on a taxi?

    Just charged last night in Gilroy and highest rate we saw was 99kW, not shared. Believe people using some of the newly installed chargers there said they were charging over 100kW so I think as they've expanded things have gotten better...at least in the area we frequent.
