I don't know what's going to happen with this project of his, but this certainly is an interesting article: >Sitting cross-legged on a dirty, formerly cream-colored couch in his garage, Hotz philosophizes about AI and the advancement of humanity. “Slavery did not end because everyone became moral,” he says. “The reason slavery ended is because we had an industrial revolution that made man’s muscles obsolete. For the…

Regarding slavery that's a fatalistic attitude that's not very good for the advancement of human societies. The other side of the coin of his "technology outgrew slavery, and thus we got rid of it", is that if tomorrow's technology demands some moral monstrosity, to "work better", we can't but bend over and accept it. Neither human struggles (from the civil war to MLK and Rosa Parks), nor desires and leadership come…

I agree. But still quite an interesting article, one of the more entertaining reads I've had in a while.

Surprised that no one else commented on this: It is completely mad and irresponsible to test a self-driving car on a public highway especially since the one who has built it admits that he has no idea what it is doing. Hotz is putting other people's lives in grave danger and everyone is applauding him for that.

Hardly. Way worse stuff happens on the road by dumber people. I bet if he was pulled over, cops would probably be impressed then order it towed to his house. No charges.

What do you think would happen if his contraption caused an accident with multiple fatalities?

Path planning shouldn't require a ton of lines of code, really. I've seen in-use path planning and localization in the sub<2K LOC range.

In 2007 for the DARPA Urban Challenge, the Benn Franklin Racing Team used Matlab for their car. The entire thing ran on 5000 lines of code compared to similar performing cars written in C/C++ which used over 100K lines of code. http://velodynelidar.com/lidar/hdlpressroom/pdf/Articles/The...

That is true, and was very impressive. Consider how expressive matlab is though - x = A\b is one line in a .m file, but can correspond to several hundred of lines of fortran.

>the one who has built it admits that he has no idea what it is doing When did he do that?

No time to read the article again to find the quote but the problem is really inherent to the technology. It is very difficult to know what a neural network extracted from the training data, and therefore it is extremely hard to know how it will behave in the future and especially in emergency situations that were not part of the training data.

Interesting to see an nvidia shield box on his shelves [0] - I've been playing with one, and the Tegra X1 SoC in there is an absolute beast. Nvidia are pushing this chip for automotive, supported by freely available learning and vision toolkits.

I'd not be surprised to see some interest and support from nvidia on this (if not, then they should REALLY look into it).

The 21" monitor portrait-style in the car is fantastic. The testing of a hacked-together system on the public road is not. He probably won't kill anyone, but if he were to I suspect he'd get the book thrown at him in the way that everyday death-by-DUI drivers don't. Actually I'll go futher with this criticism: we've just seen drones being FAA regulated because users were unable to refrain from doing dangerous or nuis…

Yes, holy shit does it look unsafe !

There's a good reason began on closed courses, imagine a kernel panic locking the car on a busy freeway...

Looks like the car he is using already comes with adaptive cruise control and lane keeping assist[1]. Can someone with more knowledge on the subject chime in on how/what he is doing that improves upon those?

The guy clearly is technically brilliant. But I was referring to the results. Not how the results were achieved. In the video, he claims to want to achieve level 3 driving. Let's see how he can do the following under non-perfect conditions: - switching lanes - stopping at lights - turning cornerns - turning left corners in traffic Then we can move on to the more difficult situations.

I feel as though there are improvements that can be done in the environment of driving; Have all stop lights have a beacon that will tell cars their state, "the light is green on north south, red on east west" Have exit signs have beacons as well.

Have you thought this out? What happens when someone hacks their own beacons for lulz? So then the beacons have to have public key cryptography. Now all of the firmware will need to be audited and kept updated. Will there be over the air updates? What if someone cracks or steals the key? It seems to me that a target as juicy as "getting control of the North American road network" would be worth a major national power throwing a significant fraction of its resources at it, so that inflates the computing power such devices will need.

Well that makes sense, given that basically all machine learning is transformations over matrices and that is Matlab's bread and butter. The equivalent C code might perform better when optimized, but it is going to be far longer and uglier. There's a reason a lot of ML work is prototyped out in Matlab first.

You're aware that "auto pilot" literally means "self driver", right?

It means staying on a set course. Not the same thing, right?

A "fancy autopilot" can take off and land.
