The much bigger news is they completely walked back FSD (full self-driving) into something that you have to monitor at all times by changing the description on their website. The release of a proprietary charger is somehow completely overshadowing that news. It's changed from driving itself around in a ride hailing network to earn you money while you sleep, to now making you always be in the car and pay attention and…

Precisely why I said in the past here that it was a big mistake to fit all model 3s with self-driving hardware making the car significantly more expensive in terms of cost to build. Musk once again overestimated by a long shot how good and safe autopilot will be. At least it seems he is becoming more responsible or maybe he is forced to by the new board.

He recently publicly announced that Tesla drivers will be able to fall asleep at the wheel and wake up at the destination by the end of next year. Doesn't sound like a lot changed in his mindset.

Porsche has had 350KW charging since 2017.[1] A 350KW charging station went into Livermore last year.[2] Tesla is only at 250KW. [1] https://electrek.co/2017/07/14/porsche-350-kw-ev-charging-st... [2] https://electrek.co/2018/12/06/electrify-america-first-350kw...

Now, all they need is the car...

The amount Elon has delivered so far this year alone at Tesla and SpaceX is tremendous then you see a headline where he landed a 50+ million tunneling deal on the side because why not. Staggering.

Which makes the Tesla bear cabal so disappointing.

Sounds like a good chance of waking up at the "final destination" or at least waking up having sent a pedestrian there.

This is awesome. I'm particularly happy about the on-route battery warming. Since I can't charge at my apartment, I tend to charge my car in the morning. If it is around freezing temperatures, it will charge at a rate of 0 miles per hour.

Can you speak more to this? Similar situation. Interested in a Tesla but live in an apartment without a station but during winter have well below freezing and sub zero temps. Seems difficult.

You can make it work if one of the following is true for you:

- You can charge at work (at least 6kW aka Level 2)

- You drive less than 35 miles a day and have a 110v outlet where you plan to park it overnight

- You have a nearby mall or similar with a quality level 2 charger, and you don't drive too far every day

In any case I suggest checking out the PlugShare app which has the widest collection of charging stations including estimated kW, ratings, and reviews. Select your car model and it'll automatically filter the supported charging types.

On a side note: I don't recommend relying 100% on superchargers. You can obviously combine any of the above solutions, including supercharging, but superchargers get too crowded if people keep using them as the only source.

I think you're confusing the next incremental step toward FSD with the end state of FSD. Tesla changes its marketing materials and web site copy all the time, but the Master Plan Pt 2 post (which outlines what you're alluding to) remains unchanged. Additionally, just three weeks ago, Elon was on the Ark Invest podcast claiming FSD will be safe enough for a human to sleep at the wheel by end of 2020[1]. I don't think…

And four or five weeks ago Tesla had a filing about building more stores. It seems a lot of plans are changing. Elon claiming that in a podcast isn't a promise like this text on the order page.

According to the vehicle purchase agreement and Tesla's lawyers, nothing on the order page is binding anyway (and ditto for Elon's claims). I agree they have changed the "promise" they are making to new purchasers on the page you've cited, but I don't see evidence that they are scaling back what they intend to deliver vis a vis FSD.

Pretty sure customer data isn't uploaded en masse to train networks at Tesla.

Have you ever considered how much chemical energy is flowing through the gas pump when you fill up a car?

I got curious and did the math: US gas pumps do 10 gallons per minute, which give us 0.61 L/s. Density is about 0.7kg/L, energy content is about 46.7 MJ/kg. Multiplying the three we get juuust under 20MJ/s or 20MW or about 80 times more energy than this kind of electric charger

The difference reminds me of the energy efficiency a EV has.

250KW. JFC! That's enough to power 100 average houses, all going into one car. I'm both impressed and slightly terrified.

At 250 volts, it is only 1000 Amps. Normal houses come with 200 Amp service. Older ones may be 100 Amp, and larger modern ones are 400 Amp. So that is about 5 houses. You could buy that service. I hope Tesla would sell you the supercharger for it.

250KVA is a common rating for a moderately sized distribution substation. The utility certainly doesn't put only 5 houses on one - more like 50.

His companies delivered, not him alone. Take nothing away from the man though, he works insane hours.

But he's the one coordinating it all. Which is impressive. It's often difficult to run a single small business let alone a single large project/company. It's quite outstanding to be able to run multiple of them simultaneously.

He's not exactly coordinating it all himself. I doubt SpaceX would be doing anywhere near as well without people like Gwynne Shotwell.
