I like to check for ranges and limits
Big fan of treating all inputs and outputs to and from functions as hostile. So parameters and return values as well. Always interesting how fast the bugs turn up once you start enforcing that.

while an interesting video I really want to see the entire front arc stitched together. How is it judging it is safe to go through the stop sign? Situations like that fascinate me the most. One issue not discussed enough is all this push for automation really needs road marking guidelines pushed down from the Federal level. While the feds can hold domain over the interstate system or roads it can be maddening the dif…
>> One issue not discussed enough is all this push for automation really needs road marking guidelines pushed down from the Federal level. That would be a mistake. You don't take a safety critical system and rely on a nationwide beauracracy getting all the details right to make it safe, or even effective. We've had the discussion here before, and the only way for full level 5 autonomy is a general AI capable of most…
The interstates follow very strict and powerful standards that make us all so much safer.

A neural network needs to be taught this and then all cars with that training will respond correctly forever. Every individual human would need to learn this separately from experience, which would require far more soccer balls (and children).
By "taught this" do you mean kill a kid?

> I thought fully autonomous driving was meant to be done by now? It was, but software often goes over-schedule, especially in a brand new field.
The prudent thing to do there, would be to exercise prudence. Not announce to investors and the public ever more grandiose targets after each miss. As it is we're on about Autonomous Driving Promise Mk IV from Musk, "fully autonomous, coast to coast, by the end of 2020". (That's after 2018 was missed. Which was after 2016 was missed.)
Those poor investors are really taking it on the chin today because of those overly optimistic software projections!
Not sure I'd trust an autopilot based on crude visual odometry and segmentation that can only achieve a paltry 17 fps.
Not sure I'd trust humans since their crude visual systems lead to reaction times of over one second: https://www.researchgate.net/publication/233039156_Brake_Rea... 17x faster is an impressive improvement
It still strikes me why so many people are still against a future with self driving cars. Sure, people throughout history are scared of change & new tech. But if you look at this video and compare the amount of stuff the camera catches AND processes, with the things you are seeing & processing, it's really hard for me to see me being better at it than a computer. The reality of driving (as a human) is that most of it…
The amount of jitter in the estimates makes me nervous, especially when the model thinks something is present in one frame and not there in the next.
This is a problem even in production autopilot in Teslas. When stopped at a stop light, you can see cars "dancing" and rotating randomly in a jittery fashion. Today during an auto lane change, the system blinked a truck from two lanes across in and out of my target lane, causing the car to cancel going into an empty lane after quarter ways entering it, twice.
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 ago though.
You can tell the car is a 'nervous' driver. It plays it way too safe, but I guess that's a good thing at this point.

Two issues, first: I thought fully autonomous driving was meant to be done by now? Second, don't Tesla & SpaceX have a reputation for being a terrible place to work, with Musk expecting everyone to be working as hard (or harder) than him, and firing people in weird and capricious ways.
>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…
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 at the bottom.
I do find it funny though. On the one hand Alexa only manages to turn on the lights successfully 50% of the time yet somehow we will magically have self driving cars capable of safely navigating the roads any day now. I mean for fsck sake, we don't even have a thing that can wash and fold clothes automatically but somehow self driving cars will be on the market any day.
Like, if we cannot even get voice recognition to work right, how on earth will you tell this magical car which street parking spot to take in a busy city? How will you tell it to pull over to pick up a friend? Hell, how will you tell it to go through a drive-through at McDonalds? A touchscreen?

I've gotten the impression that the "firing people in weird and capricious ways" bit has been greatly exaggerated. I do think anyone taking this has to expect grueling and challenging work. The job description practically demands that.
I like these videos, but I'd really like to see one in snowy conditions, or other less-than-ideal road scenarios. I think there's a lot more to observe and learn from in those conditions than in bright, sunny days, in well maintained streets.
