Normal roof tiles are just as ugly as solar panels. They should simply make panels in all sizes so that they cover the roof properly. You probably need only a few custom size ones. I forget who but it reminds me of electric cars with speakers to restore the engine noise. There is nothing beautiful about noise.

EVs have speakers for safety, not sonic beauty.

Both self driving craze and car tunnel madness is only possible at all because how car centric US mindset is. If you even try to suggest that people could instead use good public transport and pedestrian infrastructure they would look at you like you are some sort of crazy. Musk just takes car centric society pipe dreams and sell it back to them. Like OMG you transiting to work and can safely stay in your phone 99% o…

But transit only solves your problem in cities like London. Some people - for some reason I’m still not entirely clear on - seem to like this. But other people - so far the majority - don’t. And for those, self-driving cars solve the transit problem. That’s valuable. And you only need to beat unit economics of taxis. So there is a significant margin to capture

Self driving cars still create traffic jams and huge environment contamination No problem is solved.

I caught him a few times not writing significant details that go against his narrative. "FSD disengages just before the collision." The other video angle shows that the driver presses the brake, which disengages FSD. "Tesla consistently hides information from the court." There are two different cases separated by years. The police got all the information they needed in the first case. "FSD is 10x worse than the avera…

"FSD disengages just before the collision." The other video angle shows that the driver presses the brake, which disengages FSD. To be fair that's not a contradiction. If FSD is designed such that a user braking because FSD was about to plow into something, sure the user started driving at the last second, but that is Tesla making a design choice to artificially blame users for FSD being fundamentally unsafe.

The claim was that FSD disengages before collision without user input (presumably to fool someone into thinking that it's the driver's fault). It's not clear who they are trying to fool though. The public will not buy it. NHTSA requires reporting the crash as ADAS-related if ADAS was active at any point during 5 seconds before the crash. The court would just classify this tactic as criminal negligence in the design (if they can detect imminent crash, why they disengage FSD instead of initiating emergency braking?).

All-in-all, the trick that can't fool anyone and that doesn't make any sense. If this claim was true, the only explanation would be that Tesla is evil for the sake of evil and to the detriment to itself. Evil and dumb.

On the other hand, pressing the brake is a common way of disengaging ADAS. Tesla is no better and no worse in this regard than other ADAS manufacturers.

I don’t think it’s that good of an idea because only 50% of my roof was good for solar power (that is what faces the sun) so having the entire thing be panels is mostly a waste. I’m sure this is the case for a lot of houses. When I had panels installed, adding them on the “bad side” would only gain a few kwh.

Panels are so cheap it doesn't matter.

Regular solar panels yes, but not the Tesla panels!

EVs are required to produce sound for pedestrian safety, but they are absolutely beginning to make faked IC engine sounds for aesthetic appeal. See the Ioniq 5 and Dodge Charger EV.

Have you heard of Fratzonic? If you haven't, you can't unhear it.

Any article on Solar Roof that doesn't mention Tesla buying solar roof from Elon musk's cousin when solar roof was going under is an article not worth reading

It's not quite even that - he wanted to bail out his cousin's failing solar business with Tesla shareholders' money, but to try and justify it, they pretended that Solar Roof was a fully developed, ready to sell product that was going to be revolutionary and worth buying SolarCity for, when it was actually just a concept they'd quickly come up with and some 3D renders.

They actually had to develop it (with Tesla shareholders' money) after buying out the failing SolarCity.

If it's required, then you can differentiate your product on the market, but the regulatory requirements are driving the decision to spend money on it.

> The economics never worked either. An average Tesla Solar Roof costs approximately $106,000 before incentives, compared to roughly $60,000 for a traditional roof replacement plus conventional solar panels — a $46,000 premium. The payback period stretches to 15-25 years, compared to 7-12 years for traditional panels. Yikes that’s a lot of money. For most people buying solar, I think payback period is probably the bi…

Are these payback periods factoring in opportunity cost? If not the game is already lost. If so periods that long are so sensitive to alternate asset returns that they could easily be infinity.

Opportunity cost meaning investing with standard rule of thumb returns? I think usually it's just total cost at installation divided by the product of power generation and energy cost. So that's $ / (W x $/Wh), which should reduce down to just hours that can be trivially converted to years
