The cars are real but they are... Mediocre. The first year of ownership is an amazing honeymoon period, assuming you got one with decent build quality. But the parts are cheap, and they break quickly. I've had one for 5+ years and it's gradually become something I prefer driving less and less.

they’re electric cars. And i’m pretty sure they’re the biggest electric car brand with the most chargers, which they lease to other automakers at a profit. My family has a Tesla and they seem to be very happy with it. I’ve driven in it and it seems really nice, maybe not exceptional but not bad. I do have to say though, the Lidar and self-driving is glitchy and kind of gimmicky. But the fact they’re electric makes th…

But there are great electric cars from, eg, Kia, Hyundai, Ford, VW, etc. Etc. Tesla is no longer unique.

Ok? As a Model 3 owner for 3+ years the car shows well and has been rock solid this whole time. > Parts break difficult to replace I think I had a set of squeaky control arms that Tesla replaced under warranty in less than a week, free of charge. I don’t remember because it was such a nonissue. Side swiped by another driver; dented my fender, bumper, smashed the headlight. Their insurance took fault, Tesla certified…

Yeah, I have an older model S. It could be my model just doesn't get the care that newer ones do, and my experience reflects an "early mover" experience. But I've had to replace door handles, sensors, memory, windshield, and a bunch of other stuff due to defects. The car stutters on the road at 50-55 mph, but is fine above that.

It was awesome in 2015. It's a pain in the ass in 2022.

> As an owner for 5+ years, the cars show well but pretty quickly become a pain in the ass. I agree. As a former owner. They are fun to show. But there are real annoyances. In the case of the Model 3 in particular, I quickly tired of the door handles. The psychotic windshield wipers. No CarPlay. The smartphone unlocking which worked most of the time until just that moment when your hands were full. It became a chore…

> The psychotic windshield wipers

Until the windshield wipers are solved, I would not expect the FSD. SotA deep learning models are not good enough to control that function yet.

Tesla has bet the company on robotaxis, but their vision only tech stack doesn’t seem capable of solving it, which is a problem because Tesla has repeatedly promised FSD is right around the corner, or less than a year away. It’s hard to believe Karpathy would step down if he felt they were close to solving the problem anytime soon. This announcement comes after a 4 month sabbatical where Karpathy said he wanted to ta…

> This announcement comes after a 4 month sabbatical where Karpathy said he wanted to take some time off to “sharpen my technical edge,” which makes it sound like this is the result of frustration with the technical approach instead of burnout.

That's exactly what I would expect someone burning out to say. You feel the burnout so you need time to get over it and feel 100% (regain your technical edge). You're still burnt out after 4 months, so you don't come back.

Frustration with the technical approach can also cause burnout.

Bjørn Nyland's review of the 2022 Model 3 Performance [1] confirms your view that the Model 3 is absolutely not dated. He tests scores of EVs and still considers the Model 3 the best balance of comfort, features, technology, performance, etc. If anybody here is seriously concerned that the Model 3 may be "dated," I suggest watching the video below. [1] https://www.youtube.com/watch?v=QdMwGJBFUd4

Hahaha. Yes, very honest to link to a massive fanboy as though he's an unbiased source.

Someone who's apparently been given 4 teslas by advertising his referral code during his video reviews.. good lord.

> Elon in 2028: “time machine!” Well, to be fair, he only has to hit _that_ goal - at which point he can go back in time at his leisure and fix all the others. And he could hit even the time machine goal as late as he wants, and it won't matter.

This sounds like solid evidence for the fact that he won't ever get his hands on a time machine.

Isn't Tesla supposed to be producing Optimus, their human-like android, next year? Elon has been over-promising(i.e. flat out lying) about self-driving every year since.. 2014(there's a youtube video compilation of it)? It seems like his strategy is to just come up with increasingly grandiose promises every year when he fails to deliver on his past promises. He's trapped in his swirling vortex of bullshit. Very worry…

I don't recall Tesla ever saying they were producing Optimus as a product any time soon. He's said prototype demo later this year. A prototype is very far from a finished product. As a product businesses/consumers can buy, at least 5+ years from now.

Production ready by 2023: https://www.cnbc.com/2022/04/08/elon-musk-says-tesla-is-aimi...

The situation outside the US is even worse for Tesla. There's a whole swathe of great EVs these days from VW (ID.3, ID.4), Renault (Megane, E-2008), Opel (Corsa-e), Volvo (C40, XC40), Ford (Mustang Mach-E), Jaguar (I-PACE), Polestar, BMW (i4, iX), Audi (e-Tron), Mercedes (EQS), Skoda (Enyaq), etc. The range of models is also much wider in terms of affordability. In Europe, we've reached the point where an EV is just…

And still Teslas sell better both in EU & China than all those EVs you mentioned

Care to link a source?

Driving is a social problem, not a technical one. It's functionally the same as walking down a crowded sidewalk. The car is just a tool, just an extension of our bodies. We can't build a robot which can walk down a sidewalk without running into people either. The sensor tech and mapping fidelity are red herrings. People drive well because only people are good at predicting human behavior.

Sort of. Your wording actually assumes down to its core that driving is inherently social, when in fact I think it may be only provisionally social. Driving currently “is social” in a few senses, But of course the important (and obvious) one is that it currently involves accounting for human-operated vehicles. Alternatively, an autonomous vehicle operator in a homogenous network full of other autonomous operators has…

You know, I could be snide, and say, “We’ve already invented that — it’s called a train.” :D

But I’ve thought the same, too. If every car on the road is robot-controlled then it changes the problem. Modulo failures, discrete algorithms should behave predictably towards each other, like the unix API philosophy.

It seems hard to get there, though. Even today it’s a PITA to maintain API boundaries in simple libraries, never mind make sure that the new Tesla v12.4 Full Self Driving For Real This Time doesn’t trigger edge cases in Volvo v7.7a Actually Real Self-Driving We Promise.

Can we make software that allows cars to behave as predictably as rail cars, but without the rails? Maybe, but I expect only on limited-access freeways. I’m sure these robot-driven cars will remain incompatible with common road uses cases like pedestrians, cyclists, and children chasing balls.

Yeah, but Google's vision + lidar tech also doesn't seem any better at solving it either. They have been working on this problem the longest and they aren't even confident enough to produce a product with it. Google is probably the leader in AI and AI research. They are also the leader in data and mapping. They have billions of cash to play with. Yet it seem like they haven't gotten any closer at solving this problem…

Waymo and Cruise routinely have driverless cars on city streets. In California, all collisions, however minor, have to be reported, and DMV posts them on their web site.[1] Most are very minor. Here's a more serious one from last month: " A Cruise autonomous vehicle ("Cruise AV") operating in driverless autonomous mode, was traveling eastbound on Geary Boulevard toward the intersection with Spruce Street. As it appro…

> By not doing so, it did the legally correct thing. The other driver will be blamed for this. But it may not have done the thing most likely to avoid an accident. This is the real version of the trolley problem.

It performed the only sane solution to the problem - stopping. You can't possibly predict what the most likely thing is to avoid an accident, because there is a multitude of factors beyond just 2 cars moving towards each other. Are there pedestrians present? Other parked cars? Storefronts with customers inside? How close to the sidewalk? Trees? Construction/Debris?

Once we get AI working better than 99.9% of humans on roads with speed limits of up to 30 mph - we can expand it to faster roads and introduce advanced behaviors. But for now, stopping in uncertainty is the best available option.
