Re: Tesla's self driving algorithm's overlay [video]
#2I have often wondered about this, so I do find this interesting. Of all of the info presented, one question I have is how does the AI decide when to go at a 4-way stop? In real life, I'm am constantly amazed at how confusing a 4-way stop is to humans.
Not that I ever had any doubt into how complicated real-time video analysis could be, this just makes my appreciation of the complexity of the problem that much more qualified.

Yes. In theory, 4 way stops follow some simple rules -- whoever gets there first and makes a full stop goes first, and if more than one party makes a full stop at the same time, the party on the right goes first.
In practice we live in a world of (very illegal) rolling stops, people beckoning at each other to go first, people inching forward, etc.
That's not even considering some very stupidly designed four-way stops here in Illinois with two lanes on each side -- how the heck is one supposed to even figure these things out? It ends up being a game of chicken.

#4Which sensor has primacy? radar, lidar or camera?
I recall it mentioned somewhere that, after a well publicized tragedy hitting the side of a white truck on a bright day, Tesla was moving to radar?
And yet a lot of the cues this awesome video shows seems to be camera-based line detection etc?

If you look at the overlay, the algorithm seems extra paranoid about the following aspects: HIGH_BEAM, BLINDED, RAINING, TIRE_SPRAY, which all sound like camera weaknesses, not lidar/radar weaknesses. My guess is that this is camera-based still.
Also interesting is the vision fps of ~13. That's 75ms latency.

#7I believe this was released as part of Tesla's Autopilot hiring announcement. More details here:

Definitely someone's dream job ;) I particularly like the applicant query: "Tell us, what extraordinary work you have done?"

Google had to program their car to stop treating 4 way stops exactly as the law required, and instead pretend to be a little aggressive: https://www.nytimes.com/2015/09/02/technology/personaltech/g...

IIRC tesla still doesn't use LIDAR. Just wanted to point that out.

The algorithm I apply is actually pretty simple: First at the intersection goes first. So you, individually, should let everyone who was there when you arrived go before you, but you should go before everyone who arrived after you.
It gets messy when people try to be polite or don't understand the rules correctly, but otherwise it's pretty easy.
It might depend on your jurisdiction, though.
