Raj Rajkumar, who researches autonomous driving at Carnegie Mellon University, thinks those assumptions concern one of Tesla's key sensors. “The radars they use are apparently meant for detecting moving objects (as typically used in adaptive cruise control systems), and seem to be not very good in detecting stationary objects," he says.

That's not nearly as crazy as it may seem. Radar knows the speed of any object it sees, and is also simple, cheap, robust, and easy to build into a front bumper. But it also detects lots of things a car rolling down the highway needn't worry about, like overhead highway signs, loose hubcaps, or speed limit signs. So engineers make a choice, telling the car to ignore these things and keep its eyes on the other cars on the road: They program the system to focus on the stuff that's moving.

They mean focus on the stuff that's not moving very fast, right? Isn't movement detected as being relative to the radar unit? So other cars are moving more slowly than signs and utility poles flying by?

yes, that's not worded very well. iirc, they also make an assumption that any vehicle they identify while moving is also moving, because they're on a highway (at least back when AP was only for use on limited access highways). of course it's very obvious how this assumption fails, but that's never slowed them down any.

I still maintain that the "drivable space under a truck" thing is because the system can't reliably tell the difference between a truck and a billboard and they had to add in the exception to avoid the system slamming on the brakes on interstates.

quote:


WASHINGTON (Reuters) - The back-up safety driver behind the wheel of a self-driving Uber Technologies test vehicle that struck and killed a woman in Tempe, Arizona, in 2018 was charged with negligent homicide, prosecutors said on Tuesday.

Rafael Vasquez, age 46, who is also known as Rafaela, pleaded not guilty on Tuesday after being charged in the death of Elaine Herzberg on Aug. 27, court records show. She was released pending trial set for February 2021.

Herzberg died after she was struck while walking a bicycle across a street at night. The first recorded death involving a self-driving vehicle prompted significant safety concerns about the nascent autonomous vehicle industry.

Uber declined comment. A lawyer for Vasquez did not immediately respond to a request to comment.

A Tempe police report said Vasquez was repeatedly looking down instead of keeping her eyes on the road. Prosecutors in March 2019 said Uber was not criminally liable in the crash.

“Distracted driving is an issue of great importance in our community,” said Maricopa County Attorney Allister Adel. "When a driver gets behind the wheel of a car, they have a responsibility to control and operate that vehicle safely."

Police said previously the crash was "entirely avoidable" and that Vasquez was streaming "The Voice" TV program at the time of the crash.

In November, the National Transportation Safety Board (NTSB) faulted Vasquez's inactions and Uber for inadequate attention to safety and decisions in the company's autonomous vehicle development.

The NTSB said the probable cause was Vasquez's failure to monitor the driving environment “because she was visually distracted throughout the trip by her personal cell phone." She was supposed to act in the event of an emergency.

Uber made a series of development decisions that contributed to the crash's cause, the NTSB said. The software in the modified Volvo XC90 did not properly identify Herzberg as a pedestrian and did not address "operators’ automation complacency."

Uber deactivated the automatic emergency braking systems in the Volvo XC90 vehicle and precluded the use of immediate emergency braking, relying instead on the back-up driver.

read that last line, they did that to stop it from braking all the time.

also lol at Uber not bearing any responsibility

It's just a giant manually ordered if-then-else decision tree. Every single time a new variable is introduced (like an overpass or someone has a bike with training wheels) everything has to be rethought. What if there is someone in the middle of the road but they are under an overpass, am I allowed to hit them? It's impossible to know.

It's a great system.
yup, and I'm not sure like 99% of the people realize this.

The alternative would likely be some sort of Reinforcement Learning setup that took in various sensors and state information and output car control surface displacements. Doing this would still require heuristics for processing input and output regardless for obvious reasons.

That says nothing that no one in the world would be able to tell you why any specific output came out of any model. And, depending on the input data, methods and complexity of your output data, they may not even to be able to tell you the range of data that *could* come out.

Consider if you somehow made a ml fake noise crowd simulator.. You have the raw crowd noise from the nba for every game ever televised , so you train it up and bring it to espn and the first question they ask you is "will this accidently output swears or other offensive things" and the answer will be 'probably' and they'd be like well get back to us when it doesn't.

I'm sure I'm correct in assuming that the whole pitch of 'Tesla has an advantage for developing self-driving because their whole fleet is constantly transmitting data that continuously trains their model and helps the cars learn' and all that is total hogwash right?

Like the little I know about how ML stuff actually works it doesn't seem to make any sense. Stuff that was posted earlier showing their software being only vision-based classifiers seems to confirm this.

Like what could the cars / software be 'learning' by all this data that's supposedly being used to train their poo poo in real time?

Seems like total fiction meant to convince the less technically literate that their poo poo is the best and brightest.

99.99% horseshit.

the hard part of getting good training data is that you need to to have someone go through and classify everything in it. that requires the full video which as far as anyone can tell Teslas do not collect.

the 0.01% truth is that they do record the times and locations of where autopilot disengaged or the driver took over manually. that lets them see spots where the system is loving up. a good company would then send out a team to check out what's unique about that spot, Tesla just disables whichever classifier was causing the disengagement.

even that's not all that useful because you miss all the times when the system should have disengaged but didn't.

SFGATE: I’ve read about some Tesla batteries catching fire, and California is obviously having some issues in that department. Is any of that a concern?

MORRIS: I’ve been stuck inside for the better part of three weeks because of poor air quality, and we’ve had friends who’ve had to evacuate their homes, so it’s a huge threat.

For the first eight months, we had teams of people and machinery on the property clearing as much dead brush and hazardous material as possible, creating firebreaks, and installing water storage tanks that Cal Fire can use. Cal Fire has been instrumental in guiding our efforts with fire mitigation. We even bought our own fire truck for the property — it’s pretty awesome.

This may or may not be true, I read this anecdote a million years ago but it was about how early the USPS got incredibly good at OCR of handprinted addresses and why other OCR just still completely sucks despite the fact that the USPS system can turn what even looks like gibberish to humans into actual addresses.

Basically the answer was the USPS was using a neural net to recognize addresses and literally no one had any loving clue how it worked, not even the developers, much less how it applied to other OCR applications. Just a huge loving black box that turned handwriting into addresses.
