Don't forget illegally running autonomous tractor trailers in Palo Alto and on the roads of Nevada. These guys are criminals... total disregard for human life (but their own) in every shape and way there is. From potentially killing people, too treating everyone is who not their BRO like trash; drivers, employees, customers, business partners, etc, etc, etc... GROSS!

Your comments come off as if you are more bitter about some company you can just choose to ignore than benchamark is about Travis.

Normal humans also run red lights when the yellow-to-red light time is too short. Transit guidelines generally state that yellow lights should stay lit 1 second for every 10mph of the speed limit. When the yellow light is shorter than this, it's easy to get caught in the middle of a red.

Uber is saying that this text doesn't mean Uber knew that its self-driving cars were running the red light - instead, it refers to Uber engineers recording normal, human-driven cars running the light.

Simply unbelievable how much garbage is on that web page without an ad blocker (I put a box around the actual content that appears without having to scroll): http://i.imgur.com/0S2FIAW.png

More annoying is that even with as a IEEE member with Spectrum subscription, there's no way to log in and remove the ads, only to download the magazine.

Have you seen the video? It's way more jacked up than what you're implying:

Watch that and tell me that it's reasonable or caused by a short yellow...

I saw his reply as adding "too short of yellow to red time" to the list of "not paying attention" and "being an asshole" for human reasons to run red lights. I'm not sure why you're attacking him for a claim he didn't appear to make.

Multiple images can be used to compute a 3D point cloud. This is computer vision stuff around for many years. The challenge is this is a passive sensor in that the cameras count on light illuminating the scene. So at night; in bright light (that causes images to blow out); shadows; etc; you can have voids.

Incidentally, Musk's take: "The whole road system is meant to be navigated with passive optical or cameras and so once you solve camera vision then autonomy is solved if you don't solve vision it's not solved so that that's why our focus is so heavily on having a vision neural net that's very effective for road conditions." https://www.youtube.com/watch?v=gv7qL1mcxcw&feature=youtu.be...

Given there is no further context in the messages released I humbly submit that this "explanation" provided by the unbiased source at Uber is full and utter bullshit

Like, they are standing there taping other people running red lights? And Kalanick cares how, exactly?

No, this is them taping their own cars running red lights. Which is a very likely scenario since they are 1) testing on a small subset of streets and 2) if it makes the mistake once, bet on a computer to make it again.

I'm curious as to what happens when there are two cars with active sensors at the same place - how much would they interfere with each other?

Elon has publicly claimed that he will be able to provide an L5 autonomous car without using lidar in the next few years. AL, another expert in the field, believes that claim is so ridiculous that he must be willingly lying, not just overconfident.

Musk said they'd demo L5 late this year, which is delusional.
