Compare Google's system from five years ago.[1] (at 7:42) This new video is at n00b level compared to that. [1] https://embed.ted.com/talks/chris_urmson_how_a_driverless_ca...

The camera is bird's eye on the google presentation. And it is a recording. So jitter/flicker can be cleaned up/smoothed out and the data can be massaged in ways that a real time system may not be able to do. This is a presentation. I'd be /very/ surprised if this animation was from RAW data as-is. Also there seems to be Lidar data (point clouds) which Tesla doesn't have. So while this means bounding boxes may have l…

The car is aware where it is in the world, so a birds eye view is more representative of what the waymo car actually sees, it’s just one of the many ways the waymo car has better data to work with

>I thought fully autonomous driving was meant to be done by now? Musk was bullshitting when he made that prediction. Maybe he did it because he had bought his own bullshit. Personally I think what's more likely is that he was cynically conning people. In reality, I think no-one is anywhere close to fully self driving cars. I would be surprised if we saw fully self driving cars any time in the next 50 years. The whole…

> for some reason often believed by otherwise quite smart people I don't understand why so many smart "tech people" fall for the hype. Maybe it is because "machine learning" is just abstract enough that even the most jaded developer thinks they can treat it like a black box where if you pour enough videos, photos and LIDAR readings for training into the top it will somehow spit out a fully autonomous self driving car…

You can’t imagine a way to do this, therefore it’s impossible?

Note that Google's system operates in pre-mapped areas and uses lidar.

So it operates under the conditions that we expect the commercially available product to operate under? Yeah cool thanks for the caveat.

No, it operates in an infintessimaly small test area.

Plus Tesla still does not report disengagements to the CA dmv, right? It seems so strange to me that their HQ is there and they do not report any testing there.

Why is that strange? Does Tesla strike you as conventional?

As to "tech people" falling for the hype, it all depends which particular hype but: "surprised if we saw fully self driving cars any time in the next 50 years." a couple of years after there have been self driving cars driving around Arizona https://youtu.be/aaOB-ErYq6Y?t=93 reminds me of quotes like "The aeroplane will never fly." — Lord Haldane, 1907 a while after the Wright brothers had done many flights. You coul…

Rather expensive self-driving cars, with safety drivers have been driving around a very small part of Arizona, right? That's not really that close to an affordable self-driving car that I can take overnight door to door from the bay area to the Los Angeles area while I sleep. That may not be 50 years away, but it sure doesn't seem any nearer than 20 years. Progress towards something usable has been pretty slow, and t…

A percentage of the trips have been without security driver for several months. As for affordable they are comparable to Uber and lyft and you can actually get a Waymo trip using the lyft app, so that seems pretty affordable to me.

No, actually it is not. It basically throws the operator into the worst possible conditions. Remember that the whole point of self driving cars is to eliminate the human driver. A driver who doesn’t drive is not capable of taking over from a machine which just gave up on recognizing what’s happening due to the severe weather. An example from my own backyard. My car is equipped only with ACC and lane assist. I already…

Computers have already been judging the conditions you cite better than humans for a long time. Your car is equipped with anti-slip systems that do a far better job both controlling the car in bad conditions and recognizing those conditions than you can. Frankly, I'd trust a computer over the average human any day, given the horrible judgement I've seen most people exercise on the roads.

> Computers have already been judging the conditions you cite better than humans for a long time. Your car is equipped with anti-slip systems that do a far better job both controlling the car in bad conditions and recognizing those conditions than you can.

Only when they find themselves right on that surface. They’re not able to predict this before the situation occurs.

"Inside Waymo's Secret World for Training Self-Driving Cars" -The Atlantic

https://www.theatlantic.com/technology/archive/2017/08/insid...

This was a really really good read, especially into how Waymo simulations could generate data like seen in this video. It's from 2017 but still an extraordinary article for the quality of engineering insight.

Waymo is at least 5 years ahead of Tesla. They are running driverless self driving cars already on city streets. My Model 3 can’t even navigate a parking a lot half the time I use the summon feature.

Of course the software running in the current Model 3 can't compete with Waymo, that's a idiotic demand. That is just arguing in bad faith. We have no clue how far they are as that software is internal.
