part12.939CA2A0.4A9FFDBF@princeton.edu”>Tesla’s autonomy event: Impressive progress with an unrealistic timeline
T. Lee. April 24, "There’s an old joke in the software engineering world, sometimes attributed to Tom Cargill of Bell Labs: "the first 90 percent of the code accounts for the first 90 percent of the development time. The remaining 10 percent of the code accounts for the other 90 percent of the development time."…
You can think of self-driving car development as occurring in two stages. Stage one is focused on developing a static understanding of the world. Where is the road? Where are other cars? Are there any pedestrians or bicycles nearby? What are the traffic laws in this particular area?
Once software has mastered this part of the self-driving task, it should be able to drive flawlessly between any two points on empty roads—and it should mostly be able to avoid running into things even on crowded roads. This is the level of autonomy Musk has dubbed "feature complete." Waymo achieved this level of autonomy around 2015, while Tesla is aiming to reach it later this year….
In this second stage, a company also needs to handle a "long tail" of increasingly unusual situations: …Waymo has spent the last three years in the second stage…
Tesla says that’s a 21-fold improvement over the Nvidia chips the company was using before. Of course, Nvidia has produced newer chips since 2016, but Tesla says that its chips are more powerful than even Nvidia’s current Drive Xavier chip—144 TOPS compared to 21 TOPS.
But Nvidia argues that’s not a fair comparison. The company says its Xavier chip delivers 30 TOPS, not 21. More importantly, Nvidia says it typically packages the Xavier on a chip with a powerful GPU chip, yielding 160 TOPS of computing power. And like Tesla, Nvidia packages these systems in pairs for redundancy, producing an overall system with 320 TOPS of computing power…. Regardless, both companies are working on next-generation designs, so any advantage either company achieves is likely to be fleeting….", Read more Hmmmm… An absolute MUST read. Alain

N. Boudette, April 22, "Elon Musk, Tesla’s chief executive, has made plenty of bold predictions. They don’t always come true.
On Monday, Mr. Musk said the company was on the cusp of making cars that could drive themselves safely on any road. He also promised that the company would begin operating a fleet of driverless “robo taxis” by the end of next year.
“I’m very convinced,” Mr. Musk said in a presentation to analysts at the company’s headquarters in Palo Alto, Calif. “In the future, people will want to outlaw people driving their own cars because they’ll be unsafe” compared with autonomous vehicles….
He said Tesla had developed “the world’s fastest computer” for use in self-driving cars, able to conduct 144 trillion operations per second. Nvidia, a leading maker of chips for automotive use and a former supplier to Tesla, disputed that claim, saying it had a computer that can run 320 trillion operations per second….
Mr. Musk’s lofty prognostications about self-driving cars and the new business of robo-taxis came as investors are bracing for troubling news from the electric carmaker. On Wednesday, Tesla is expected to report a loss for the first quarter amid slumping sales. The company previously said it delivered 63,000 cars in the quarter, down 31 percent from the fourth quarter, despite beginning sales of its Model 3 sedan in Europe and China…."

M. Burns, April 22, "…“Lidar is a fool’s errand,” Elon Musk said. “Anyone relying on lidar is doomed. Doomed! [They are] expensive sensors that are unnecessary. It’s like having a whole bunch of expensive appendices. Like, one appendix is bad, well now you have a whole bunch of them, it’s ridiculous, you’ll see.”
The topic was brought up by a question about if Tesla’s just-revealed self-driving hardware could handle input from lidar. Tesla’s vehicle’s currently uses several sources of data to acquire autonomous driving: radar, GPS, maps, ultrasonic sensors and more. But not lidar like some of Tesla’s chief competitors. Elon Musk previously explained that he views lidar as a crutch for self-driving vehicles. For Tesla, cameras are the keys to the future and its CEO sees a future when cameras will enable Tesla to see through the most adverse weather situations…." Read more Hmmmm… A clear line in the sand.

C. Schubarth, Pril 26,"…"Anyone relying on lidar is doomed," Musk said at an investor event on Monday, calling the technology — which most of the companies that are working on self-driving vehicles are including in their plans — "expensive" and "unnecessary."
Marta Hall, president of the San Jose-based Velodyne, said Musk’s comments are adding to confusion about autonomous vehicles: "I say this because of my concern for the roll out of the autonomous project without undue tragedy," she said in a statement. "When it comes to Tesla’s claims, ‘consumer beware,’ is advised." Hall argues that Tesla and Musk have conflated being "almost autonomous" with becoming "fully autonomous."
"Velodyne takes the position that ‘autonomy,’ implies that a car can drive safely and do all functions while a driver takes a nap," she said. "Tesla offers what are really ‘driver features,’ not autonomy. They are cool features that are fun, but not for napping."…" Read more Hmmmm… I fully agree, semantics are fundamentally important, especially wrt the need for adult supervision.

R. Csongor, April 23, "First, Tesla is raising the bar for all other carmakers.
Second, Tesla’s self-driving cars will be powered by a computer based on two of its new AI chips, each equipped with a CPU, GPU, and deep-learning accelerators. The computer delivers 144 trillion operations per second (TOPS), enabling it to collect data from a range of surround cameras, radars and ultrasonics and power deep neural network algorithms.
Third, Tesla is working on a next-generation chip, which says 144 TOPS isn’t enough….
That’s why NVIDIA is the standard Musk compares Tesla to—we’re the only other company framing this problem in terms of trillions of operations per second, or TOPS. But while we agree with him on the big picture—that this is a challenge that can only be tackled with supercomputer-class systems—there are a few inaccuracies in Tesla’s Autonomy Day presentation that we need to correct.."

part79.6547D2A4.DDF09CA2@princeton.edu”> An MIT study found that Tesla Autopilot users were better than expected at taking over before potentially dangerous situations
M. Matousek, April 26, "A study from Massachusetts Institute of Technology (MIT) researchers found that participants were better than expected at taking control from Tesla’s Autopilot system before potentially dangerous situations, adding a new layer to the debate about semi-autonomous-driving systems… Tesla has presented data that indicates drivers get in fewer accidents when Autopilot is activated, but the data doesn’t provide enough detail to isolate the effect of Autopilot from other factors, like the fact that fewer accidents occur on highways, where it appears Autopilot is most often used, than on residential streets. Fatal accidents involving Autopilot highlight its limitations, but are too anecdotal to draw broad conclusions.
The MIT study, titled, "Human Side of Tesla Autopilot: Exploration of Functional Vigilance in Real-World Human-Machine Collaboration" sought to observe how well Autopilot users were able to remain aware of their surroundings and take over from the system when necessary. The researchers looked at 8,729 instances in which Autopilot was deactivated, either by the driver or the system itself, before encountering a potentially dangerous situation, and how quickly the driver reacted to it. (Each of the 21 vehicles included in the study had cameras filming the driver, the vehicle’s interior, and the area in front of the vehicle.)
If the driver took more than one second to react to the potentially dangerous situation, the researchers designated the response as being late. Drivers responded late in none of the 8,729 instances in which Autopilot was deactivated before a potentially dangerous situation, a result that surprised the study’s authors…." Read more Hmmmm… This is an impressive finding. All previous thoughts/comments have been anecdotal or conducted in simulators. This looks real.
