If Musk actually said this he's an even bigger idiot than I gave him credit for. He makes the best cars in the world (obviously IMHO) and that's worth a lot more than 0. I couldn't give less of a damn if they can't drive themselves.

It was exaggeration as a figure of speech to suggest that if self-driving is solved, it will make the EV business look incredibly small. What's shocking is how many people interpreted it literally--that the value is literally zero without self-driving--as if the successful EV business is in fact unsuccessful.

Well, Musk said recently that the value of Tesla is 0 without FSD. Does anybody seriously think Karpathy would step down if FSD was really close to be released ?? It really starts to feel like Tesla is a huge fraud which is about to be uncovered.

I ended up selling mine because the build quality started getting on my nerves. Misaligned panels that are "within spec" or interior rattles that make the ride completely unpleasant (at only 10k miles).

The tech is all right, and I got to try auto pilot at a discount. Unfortunately the phantom braking made AP completely useless with passengers who would freak out and complain. However, when it worked it was quite nice but I ended up using it way less than I'd hoped. Glad I didn't pay 12k for it!

The best part of owning the car was the insane acceleration and supercharger network at the beginning. But, that got annoying as more people started getting Teslas. Going on longer trips meant a ton of anxiety especially since some superchargers in cities would be packed. Worse, some would be out of order or slow charging. After the gimmick wore off, wasting 45 minutes to go another 2-3 hours started becoming annoying. And before someone asks why 2-3 hours, its called hills. California is full of them, and especially where I live I lose so much efficiency climbing hills.

Anyway overall I'd rate the car 5/10. Fastest car I've ever owned. Beyond that it was pretty much exactly as they described - a beta product. I'll probably try a Tesla again in 5-10 years.

Because self-driving has a bunch of tricky edge cases and most of them will kill people. Problems with hundreds of important edge cases cannot be solved by simply throwing more training data at the problem; that's how you solve AI problems in a "dumb" manner, and it works for lots of problems (like recognizing dogs in images) -- but not for self-driving. To solve the self-driving problem we need "smart" A.I., which m…

I remain convinced that "real" self driving (as in: go ahead and sleep in the backseat) will never happen without changes to road infrastructure and possibly some sort of segregation between robot-driven cars and people-driven cars.

> Things like traffic signals that actively communicate their status to nearby robot cars (more than just a red lamp that can be occluded by weather, other vehicles, or mud on the camera lens). Or lane markings that are more than just reflective paint, but can be sensed via RF. Rules around temporary construction that dictate the manner of signage and cone placement that the robot cars can understand. The cones might have little transponders in them, I don't know.

The problem you then face is that any of those could be forged / faked without some kind of way of securely validating the message in some way. You could cause absolute chaos by driving down the road broadcasting false messages. It's a little harder to hack and modify traffic light signals, for example. But we've also seen hackers screw up Tesla cars by sticking stuff on the back of their car to deliberate mislead it based on vision.

It's fun to see everybody succumbing to scaling laws. We will only have FSD when we can run realtime inference with a huge model. No amount of creativity seems to overcome the fact that bigger is better. So, let's wait Moore's law do its job.

Well look at this guy. Maybe you should take charge as the new director of AI seen as you figured it out.

What you are describing is essentially railway system.

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…

Misread “systemic engineering” for “synthetic engineering” on first go - was thinking that may be some new ai application

What if we just, you know, walk a bit more instead? Or even cycle? I hear great things.

Clearly you live in a large city and find everything you want there.

I was prepared to buy a Tesla, and even planned on doing the full acceptance process (https://github.com/polymorphic/tesla-model-y-checklist) at the factory (a short drive from my house) but after Musk announced the Model Y was losing the radar and reading a bit more about their problems with FSD Beta (which I was planning to spend $10K to get), I concluded their cars were not the best in the world. I went and got a toyota which could pretty much have the engine compartment welded shut for ten years (modulo oil changes) and run perfectly.

It's a real shame because in principle having a manufacturing facility making great electric cars in the bay area would be a real win. Musk's reality distortion field is cracking.
