As a person who’s owned some luxury cars in their life, going from a BMW to a Model3 feels like a really big downgrade in so many ways. I can give a list of reasons why I didn’t buy an M3P at the time but quality, lack of repair options and really shitty interior topped the list. Not having carplay/android auto or satellite radio were minor but still annoying in a car that cost so much money.

We've had the complete opposite experience with our BMW->Tesla move. Sure, the BMW had a very nice interior, that complaint gets a tons of play online, and it's not inaccurate. But you know what just blows that away? Getting into a car on a 100 degree day, and instead of scorching my skin on the leather, like I would with our old BMW, the seat is cold because I tapped a button on my phone 5 minutes before when we wer…

>Music that picks up right where you left off when you come back.

I have this feature in my 2008 Renault Twingo.

I've yet to be in a country were sales are not skewed toward local cars. Sweden lots more Volvos than anything else (and definitely Teslas), France, lots more Citroen and Peugeot than anywhere else, Australia: Holden and Ford, US: lots of cars that drive nowhere else (GM, Chevy...). Regarding outselling most other car manufacturers: this seems to be the Tesla realitity distortion, it is likely true for electric cars…

Australia has no local car manufacturers and hasn't for some time. Toyota is by far the biggest car seller , followed by Mazda and Hyundai. https://www.carexpert.com.au/car-news/vfacts-australias-2021... Tesla seem to have sold 12,094 locally last year, putting them at 18th on that list. https://www.carsguide.com.au/ev/advice/how-many-teslas-are-t... Australia with its long drives if you leave a city and lack of infr…

I know Toyota closed it's Melbourne plant in 2017 (Holden and Ford had stopped manufacturing even earlier IIRC). I would argue though that Ford and Holden (which I just read ceased operating in 2020) are still perceived as Australian car manufacturers by most. They definitely had some cars specifically for the OZ market.

Hypothetically, Tesla would spin this story differently in no time if they are making great strides in a cheap solid-state radar. For now, though, it looks like Tesla is building a case after they decided to do away with radar. I recall EM saying that it looks ugly and expensive too. I really got confused when Telsa came up with this patent though https://twitter.com/iamkellex/status/1534240730633236480?s=2... No one…

The ability to cut through rain, fog, and snow is precisely why so many companies use radar based systems - that's arguably when they are the most important and useful. Leaning further into their vision systems when their vision systems cause their cars to slam into emergency vehicles that aren't even in travel lanes, and to rear-end tractor trailers, isn't encouraging. Musk is placing the rest of us at risk and I'm…

Have you seen a recent video of their most recent vision stack in use by a customer?

I'd love to see the convincing data RE: radar - they're using the same radars as every other car that has emergency braking from the car in front of the car that's in front of you. I've not heard of many "phantom braking" sessions from these other vehicles - I may have missed something.

They were using the radar for lane guidance. That's why they had to have a whitelist of locations where the radar was false triggered by the roadside environment. It never actually worked properly and they just papered it over with a hack to temporarily blind their input.

None of what you have said is true.

Was the Tesla being driven in the FSD mode? or was this a simple human error?

My $20k Mazda won't allow me to rear-end somebody even if cruise control is switched off. Neither will my wife Subaru.

With the removal of radar, they showed some pretty convincing data that the radar was too noisy to be useful, especially with discriminating things like highway overpasses vs. stopped cars. They showed that vision could already outperform radar. With these parking sensors it's different. They have no current alternative and it will cause a pretty significant loss of functionality. Disappointing move.

Some pretty convincing data that they handpicked to make themselves look good and pretend they don't need a radar, a lidar and that vision only is good enough. Perpetuating a pattern of lies from Tesla, ever since they started on self driving.

You don’t need to take Tesla’s word for anything. Their latest vision stack is in the hands of ten thousand customers, some of whom regularly post their drives on YouTube.

There are multiple tells that this move, just like the removal of radar, is supply-chain and cost-driven and not actually driven by engineering. If this were a planned move, the software would already be ready to replace it. It is not. Cars without radar still aren't at parity with the car that have it, although they "fixed" this a few weeks back by simply turning off the radar on the older cars. The parking sensors…

> downright dishonest to characterize it as some kind of leap forward Does anyone expect anything else from Tesla at this point?

Does anyone expect anything else from any corporation? Of course they are not gonna say "I'm sorry, we had to make your experience worse", of course they will try to spin it into something positive. Almost every for-profit company does this. Not to take away that it's shitty, but it's reality.

Allow me to take you for a drive in my Volvo V90. I turned the auto-braking feature off entirely because it spits false positives like crazy. Parked cars, signs, birds, cars travelling through roundabouts across my nose, nothing at all - they all trigger it, and the car stomps the brakes extremely hard. The 2017 VW Golf it replaced was FAR better - maybe two false positives in 5 years. The Volvo? Daily.

> birds Birds you're about to hit with your car? That sounds like a great feature.

But we already have a deal with the birds...

Geohot was right. Tweet re: LIDAR, but still: "When this delusion ends and all these companies fold, it won't be LIDAR vs. Or ride sharing vs. None of this matters. All that matters is building an intelligent machine. Self driving is 100% a software problem. Given software written by God, a smartphone can drive a car." https://twitter.com/comma_ai/status/1577045884159676416?s=20...

Musk has said similar things in the past; that cars should be able to do everything human drivers can do with only vision, because that's all human drivers have (discounting the far more minor sensory inputs like sound and touch). I find that take fascinating. Its, in effect, saying "well, computer hardware and the human brain are similar enough; the human brain just got an evolutionary headstart on its software, so…

I remember seeing some studies suggesting that vision training of artificial neural networks forms "similar" structures to the human brain. I don't think the brain is that magical compared to modern DL.

> it will be running on hardware that looks nothing like what I'm typing on.

Depends: are you "typing on" a TPU?
