It's a fascinating video. Does anyone know of a similar video by Waymo, Cruise, Uber, etc? Love them or hate them its pretty cool Tesla put this video out at all. Certainly gives us all a lot to talk about.
There used to be a lot 5+ years ago.

Maybe it's just that some of these "tech people" are not that smart at all?
The crux of the problem is you have people who although may well be cabable of driving to work--they are by no means cabable of understanding driving at its essence. They will never, not ever; be able to create a car that can also interact with human drivers because they don't understand driving. Period... end of story.

I think 50 years is being overly pessimistic. Self-driving in temperate climates is probably pretty close ( [1]: https://techcrunch.com/2019/09/16/waymos-robotaxi-pilot-surp... [2]: https://www.theverge.com/2019/10/10/20907901/waymo-driverles...
The thing is, I see no way to have full self driving without AGI. And I don't think humanity is anywhere close to developing AGI. Without AGI you can have level 4++ self driving, maybe, but not level 5.
> The thing is, I see no way to have full self driving without AGI.
Why? AGI seems like a significantly harder problem than self driving cars (itself a hard problem admittedly).
What I personally think will happen is we'll meet somewhere in the middle: we can redesign roads/cars to make solving the problem of self driving easier.

#454I understand that it is common to use Hough transforms to detect lines, which is critical in driving to understand lane markers and so on.
In my experiments with the implementation in OpenCV I haven't gotten good results, especially with noisy detections of lines that aren't there. But here they seem to get good line detection without many false positives, despite difficult properties of the image such as worn down paint and low contrast between the paint and the pavement. Anyone know what they are doing that works so well?

Isn't that exactly what the federal government has done to extrodinary success with the interstate system? The interstates follow very strict and powerful standards that make us all so much safer. https://en.wikipedia.org/wiki/American_Association_of_State_...
I drove across the US 5 times in the summer of 2019, almost excursively on interstates (the 40, 70, 80 end to end). I can assure you, there are hundreds of times that "strange" things happened to the road. Odd or incorrect lane markings, no lane markings, lanes beginning from the right and left, lanes ending suddenly on the right and the left, lanes marked as merge that were not, lanes not marked as merge that were,…
The vast majority of the US interstate system involves two lanes each way with a wide median separating opposite traffic flow. There is always ample signage around exits, interchanges and whatnot. There is also a stretch that is straight and level enough to be used as a runway in wartime. I think most inclines are restricted to a max 6%-6.5% gradient (for reference, I grew up on the side of a mountain and the first climb was around 14%. You could stand on that in icy conditions and would slide down if you attempted to stand on it. Most mountains passes on the interstate also have "runaway truck" pulloutss in case a semi's brakes fail.
Most of the weirdness on the interstate system is usually caused by cities; having to adapt to preexisting conditions. As an example, I offer up Chicago. i290 is a mess. The Austion and Harlem exits are both left-handed exits. Worse yet, oncoming traffic are both given protected turns from the ramps. A lot of people dont follow the law and turn into the nearest lane. A lot of people drift, and a situation like this just breeds accidents. This is in oak park, a near west suburb. The Edens expressway (I90) also had expresslanes, which causes confusion, too. Not always open at the same time or direction.

The dancing cars were fixed several months ago in an update. The computer used to just recognize cars, and then align them according to the lanes it sees. At a stoplight it when it had trouble seeing the lanes clearly the cars would rapidly change orientation. Since they updated the neural net to also recognize the vehicle orientations the dancing has stopped. I have seen a lane change cancel recently, a couple weeks…
I'm pretty sure that they "fixed" the dancing cars problem by applying a low pass filter to the data before sending it to the visualization, just so people would stop complaining about it. I think there's still a lot of jitter in the underlying data.
Seems like it would make more sense to model the inertia. Cars don't randomly accelerate at 100,000m/s/s in some direction they aren't pointed. Though they should have a model for detecting obstacles in the view regardless of inertia, because sometimes something really does appear in front of you in a thirteenth of a second.
You could probably model inertia with n prior frames of probability fields.

Agreed. It also said it was running at 13fps. Not stoked about a vehicle going 70mph updating at 13fps.
Tesla says their "Hardware 3", which is what you get if you buy it now, can process all cameras at 60fps.
seems weird to me that it's not taking any visual data at higher frequency than that.

The way you suggest the future of automotive transport rests on a fast food chain drive through suggests a kind of astroturfing social media advert. If burgers were that important, the burger company would partner with the self driving car company and find a way. None of those things are physically complex - the car will be able to see or lidar if a space is big enough for it to park in, pulling over to pick up a fri…

Honestly, I think I'm fine piloting a Tesla through a drive-through if it means I can eat on the road. I'll take 80% of possible performance / [aptitude?] now (heck, even 50-60%, as long as it's safe enough) versus 100% of possible scenarios being covered at some far-off point, especia)y if my enjoying 50-60% of capability actively gets the remaining % closer.

Or people, for that matter, who break the speed limits like 99% of the time and regularly smash their cars into eachother?
Five over is still an acceptable rate, right? Okay, good.
I drive I88 outside of Chicago. The typical speed is in the 80-85 mph range, while the limit is 60 (I drive opposite prevailing traffic). Prevailing traffic is a parking lot for my entire 15 mile commute.
