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.
When did he do that?
Prototypical case of the 80/20 rule. He has implemented the happy case. But that system is nothing people realistically would want to drive their cars. What he did is impressive. But the results are not that outlandish for a talented person. 1) Hook up a computer to the CAN-Bus network of the car [1] and attach a bunch of sensor peripherals. 2) Drive around for some time and record everything to disk. 3) Implement so…
Why is the first comment on HN minimizing this truly impressive project? Of course it's not perfect, he's ONE person.
> “I understand the state-of-the-art papers,” he says. “The math is simple. For the first time in my life, I’m like, ‘I know everything there is to know.’ ” Yep, he's still in his twenties.

Millions of drunk people drive on the roads. People can buy assault weapons, with no training and background checks. People who make self-driving software should be the least of our concerns.
There are laws against drunk driving (and harsh penalties for those that are caught), and you can't buy a firearm without a background check from a dealer (with more states requiring gun show dealers perform background checks now, too). People building untested self driving cars is an entirely legitimate concern.

"Prototypical case of the 80/20 rule. He has implemented the happy case. But that system is nothing people realistically would want to drive their cars." I'm painfully aware of this. Ten years ago I ran one of the 2005 DARPA Grand Challenge teams. That's about what we produced with less than three full time equivalent people. We didn't have to handle other vehicles, but we did have to handle off-road conditions. Ours…
> “Frankly, I think you should just work at Tesla,” Musk wrote to Hotz in an e-mail. “I’m happy to work out a multimillion-dollar bonus with a longer time horizon that pays out as soon as we discontinue Mobileye.” > “I appreciate the offer,” Hotz replied, “but like I’ve said, I’m not looking for a job. I’ll ping you when I crush Mobileye.” > Musk simply answered, “OK.” I have to agree with Elon here, Hotz is such a g…
Like most hard problems, it's easy to pick off the low-hanging fruit and claim that you have solution. Self-driving cars (in some form or the other, under some loose definition of "self" and "driving") have been around since the 20s. But it still remains a vexing problem. It is quite easy to program a car to stay between 2 cars and follow the car in front. It is quite another to have the same car drive on (a) a road…
TBH, since it's a training based system it's "just" a matter of making sure the training set is large enough, including the situations you mentioned (assuming the training method is robust, generalizes well, etc). I would love someone knowledgeable to give an estimate, but I would guess you need at least a handful (10+?1000+?) of examples of each edge case (involving bicycles, pedestrians, weird road designs, street…
The problem is: there are new edgecases born every day.
Consider, for example, an accident where the cops have set up flares. How often do you come across one of those? Very rarely, I imagine. And even if you did come across it in your training set: how does the ML know that you are following the cops' signals, and not just randomly switching lanes? That the flares are a critical signal?

2) It's probably not a disk. I'd bet it's an SSD, or something. I doubt he'd use an HDD considering how relatively cheap it is now... and considering how loaded he probably is.
SSD can also stand for Solid State Disk. Disk does not imply moving parts.

...said a guy in his 30's
Busted. Which is why I didn't say shit about what it's like to be in your 40's because ... I have no idea.
To be honest, I recommend faking to yourself that you're in your 20s still :) Much healthier attitude.
