Yeah, in many ways that would make more sense. For one thing, the sun is likelier to shine during the day, so PV electricity can go into your car. Unfortunately, the practical reality is that at home you're likely to have a garage where you can charge (though I'm of course aware that many people don't!) while at work your car is likely to be in a large parking lot without outlets. The logical conclusion is that we sh…

Body panels made of solar-cells would be nice, combined with charging from stations or at home when there is not enough sun. Is probably not doable with current technology, but maybe some day

Aren't solar-cells on the car like multiple magnitudes less power than regular level 2 chargers?

There was a lot of talk about why Tesla wasn't putting solar panels on the cars when the Model S was still new, and I thought the general consensus was it would need crazy amounts of time in direct sunlight to even make any kind of significant impact on the charge.

I mean just look at this announcement. They are talking about 250kW charge rates at peak for SuperCharging V3, and at those charge rates you'd get 75 miles of range in 5 minutes. A solar panel about the size of the car would put out maybe around 250w (give or take a lot, it's been a few years since i looked into what they can put out). Some extremely inaccurate napkin math would put it at less than a mile per hour of charge while in direct sunlight. It's just not worth it (in my opinion) in almost all cases, and probably won't be for a LONG time.

A regular solar panel is a large flat area that's oriented to maximize solar exposure. Solar cells on a car wouldn't capture nearly as efficiently. You'd be much better off spending the money on traditional PV than on putting cells on cars.

I'll not take another road trip in my Tesla after dealing with the complete lack of bathrooms between San Jose and Davis -- including at Tesla Livermore which 1. shouldn't really have been closed at that hour and 2. should leave their bathrooms open after they close and 3. there's no excuse for not providing bathrooms at every supercharger station. Oh yeah, and we only put on about a mile a minute despite the charger…

Other bathrooms are available. Your Tesla should be able to stop at those; it doesn't only stop at superchargers. One-mile-per-minute definitely sounds like something was wrong. Did you try other charging stations? How full was your battery at that point? If you've seen that with multiple stations when you battery was neither nearly empty or nearly full, I'd suggest getting the car serviced as that's not normal behav…

The poster means that they want to "kill two birds with one stone". On long trips, avoiding another stop (especially if kids are involved) is a big deal™.

The standard home contract in Italy is 3.3kW, at 230V it's less that 15 amps for a resistive load. The meter will allow you to go over the allotted power for some time before disconnecting you though (the amount of time is inversely proportional to how much your going over, and I don't think you can ever go over 4kW). Heating and stoves are gas based (ovens usually not though); going over the limit is not usual, the…

Italy used to be strange in that there were two electric feeds per house: One for low-power loads and one for high-power loads. Is that system gone now?

That's internal, right now. You don't get two lines from the grid. But you have multiple internal lines, and usually one 10A lines is mostly for the lights, other include more hungry appliances.

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.

for sure: - closed stores - no profit - lied about FSD - stock down 30% - long-term investors exit the tunnel is a joke. we were promised something, but as always with musk, we get something completely different. i'm giving the tunnel deal 3 to 6 months before imploding.

Small nobodies are typically negative about those pushing the envelope.

"Data sharing" is pretty vague but assuming you are talking about car data, it's completely decoupled from the VIN or any other identifiers that could ID you, so disabling it is just silly, but yes you can choose to not opt in.

Does "car data" include locations? There's not many people that start from area A (~500m^2 around your home) and go to area Z (~500m^2 around your office) every weekday morning, and back again every weekday evening. And yep, this applies to anything that offers vague rudimentary location monitoring.

Correct, many folks don’t realize how much can be derived about them from even anonymous data.

Personally not interested in all this auto pilot stuff anyway. Deceleration when approaching an object and rudimentary lane assist are all I’d care for and shouldn’t require machine learning.

It does include location if you stop at a supercharger. They need to know where you were in order to charge you properly. I don't think that's one you could opt-out.

I mean we are celebrating the next massive milestone of electrification of cars. Things like stock price and investors seems irrelevant

Stupid question, but who pays for the electricity at supercharger stations?

Typically, the person charging the car (well, they're paying Tesla, then Tesla pays for the electricity). Very few Tesla owners actually have free supercharging these days.

What does a close-to “fill up” cost?
