Tesla Model 3 Outperforms In New IIHS Level 2 Autonomy Tests
https://insideevs.com/tesla-model-3-outperforms-in-new-iihs-level-2-autonomy-tests/

However, it’s not perfect.
With drive assistance features becoming standard in many vehicles, it’s good to remember they’re not all the same. Some work better than others, and the Insurance Institute for Highway Safety is devising a series of tests to evaluate these systems in various driving situations. The focus of the tests is Level 2 “autonomy” as defined by SAE International, which includes adaptive cruise control (ACC) and active lane-keeping (ALK).

In IIHS’s research, the company tested five vehicles: 2017 BMW 5 Series with “Driving Assistant Plus,” 2017 Mercedes-Benz E-Class with “Drive Pilot,” 2018 Tesla Model 3 and 2016 Model S with “Autopilot” (software versions 8.1 and 7.1, respectively), and 2018 Volvo S90 with “Pilot Assist.” The Tesla Model 3 performed best through the bevy of tests – however, it wasn’t perfect.

The cars were put through four different scenarios to test their ACC. The first involved driving at 31 miles per hour toward a stationary vehicle with ACC off and autobrake turned on. Only the two Teslas failed, hitting the stationary target. The same test was then performed with ACC on, and the Tesla Model 3 slowed with gradual decelerations. All vehicles passed this portion.

A third scenario had the cars follow a lead vehicle that slowed to a stop and then accelerated. Every car performed well in this test. The final test had the test cars follow a lead vehicle that changed lanes to reveal a stationary vehicle in the test vehicle’s path. The vehicles had about 4.3 seconds before colliding with the stationary vehicle. However, all the test cars performed well with none of the vehicles striking the stationary vehicle.

One wonders if recent updates have allowed the Teslas (as well as the others) to pass this last test, as we know Tesla Model S/Xs have hit stopped vehicles in just this situation. Good news if this is something repeatable in the real world.

Where the Tesla Model 3 truly outshined its competition was in the hill and curve tests for ALK. Here, the IIHS conducts six tests on three different sections of curved roads. Only the Model 3 stayed within its lane through all 18 trials. To test how the ALK of all five vehicles performed on hills, the IIHS mapped out a course on three hills with different slopes, running six different tests on each hill in each vehicle. Here, the Model 3 had just one deficiency, touching the centerline once in 18 tests.

The Model 3’s competitors had various levels of success with the ALK tests. The BMW, Mercedes, Model S, and Volvo all went over the centerline during both the hill and curve test, with the Model S crossing the most at 12 times when being tested on the hills. The Volvo crossed the line the most at eight times during the curve test. Some of the vehicles, such as the 5 Series, E-Class and S90 had the ALK system disengage during the tests, with the 5 Series system disengaging the most. . . .

“We’re not ready to say yet which company has the safest implementation of Level 2 driver assistance, but it’s important to note that none of these vehicles is capable of driving safely on its own,” David Zuby, IIHS chief research officer, says in the study. “A production autonomous vehicle that can go anywhere, anytime isn’t available at your local car dealer and won’t be for quite some time. We aren’t there yet.”

IIHS: Fatal Tesla Crash Proves Partial Automation Is Risky
https://insideevs.com/iihs-tesla-crash-partial-automation-risky/

A headline which should elicit a "Well, Duh!" from anyone who's familiar with the past half-century or so of research in the area.

Some quotes:
David Aylor has a job with some pretty interesting perks. Recently, the Insurance Institute for Highway Safety (IIHS) manager of active safety testing has been putting miles on a Tesla Model S in an attempt to gauge the effectiveness of its Autopilot advanced driver-assistance system (ADAS). He’s found that the system has some flaws, though, if you’ve been following coverage of a handful of high-profile crashes involving the Tesla vehicles being operated on Autopilot, you likely already knew that.

In particular, Aylor points to the system’s occasional failure to properly handle road splits. It seems that there can be some confusion as to which lines to follow, and if drivers aren’t paying attention, it can lead to a collision. This appears to have been the case in one of the most famous of incidents: the crash that claimed the life of Walter Huang. That incident is outlined in a recent report about autonomous vehicles. . . .

Aylor also brings up a similar incident that was filmed by a driver in Chicago testing for this very situation not long after the Huang crash. In that case, the video of which we’ve embedded below, the car doesn’t seem to know which set of lines to follow, and the driver has to intervene, braking just in front of the gore point.

These incidents, IIHS says, are evidence of the risk that partial autonomous systems can pose. Despite the fact that they found Tesla Autopilot can reduce injuries and damage claims, it is also true that it’s not a perfect system and drivers need to be alert and ready to take control if it runs into trouble. And the problem isn’t limited to Tesla.

The report notes that vehicles from other automakers equipped with Level 2 ADAS systems have also been involved in crashes. Those occurrences, however, haven’t made headlines like those involving the Silicon Valley company. For whatever reason, none of those incidents made it into this particular report either

The report doesn’t offer much in the way of analysis, but the reason for the danger seems clear. Drivers, used to a system that works perfectly a very high percentage of the time, can be caught off guard when suddenly it experiences difficulty. . . .

The headline was probably trying to attract a larger audience than this select group, but yeah, I agree. It still looks like 'self-driving' software isn't quite ready for prime-time. Kind of a bummer for me since I'm hoping to be driven around in my dotage, which is no longer that far off...

Autonomous electric shuttle in long-term public demo in Candiac, Québec
http://www.greencarcongress.com/2018/08/20180813-candiac.html

The City of Candiac, Québec is hosting a long-term demonstration project for a 100% electric autonomous shuttle to be used on public roads for the first time in Canada. . . .

With a capacity of 15 passengers and operating at a maximum speed of 25 km/h (15.5 mph), the NAVYA autonomous electric shuttle facilitates travel and promotes the use of public transit in underserved areas.

Starting in September, the autonomous electric shuttle will provide citizens with free transportation between the park-and-ride lot and André-J.Côté Park, making its way along Montcalm Boulevard North. Stops include: City Hall, the Chartwell Le Montcalm senior's residence and several businesses.

An operator will be on board the shuttle for the duration of the project to answer any questions that users might have. This operator will also be able to take control of the shuttle as required. The shuttle will run throughout the fall until winter weather conditions take over. An experimentation phase, with no passengers, will then begin to ensure the shuttle’s performance during the winter season. . . .

The manufacturer NAVYA designs, produces and markets autonomous, driverless, electric vehicles that combine robotic, digital and automotive technologies. NAVYA has a range of two autonomous vehicles: the AUTONOM SHUTTLE, launched in September 2015, of which more than 100 have already been produced as of today and 89 sold in 17 countries and the AUTONOM CAB, unveiled in November 2017 and whose first road tests will start shortly.

Kroger begins tests of driverless grocery delivery in Arizona
Would you pay $5.95 for bread from an autonomous breadbox?
https://www.autoblog.com/2018/08/16/kroger-tests-driverless-grocery-delivery-arizona/

U.S. supermarket giant Kroger said it will start testing driverless grocery delivery on Thursday with technology partner Nuro at a single Fry's Food Store in Scottsdale, Arizona.

Kroger and rival Walmart each have teamed up with autonomous vehicle companies in a bid to lower the high-cost of "last-mile" deliveries to customer doorsteps, as online retailer Amazon.com rolls out free Whole Foods delivery for subscribers to its Prime perks program. . . .

The first phase of the test will use a fleet of Toyota Prius cars equipped with Nuro technology. Those cars have seats for humans who can override autonomous systems in the event of an error or emergency. Nuro's R1 driverless delivery van, which has no seats, will begin testing this autumn, the companies said.

"While we compete final certification and testing of the R1, the Prius will be delivering groceries and helping us improve the overall service," a Nuro spokeswoman said.

Self-driving car delivery from the Fry's store will cost $5.95 with no minimum order. It is only available at addresses within the store's ZIP code of 85257, Kroger said. . . .

Hyundai Motor completes South Korea’s first domestic autonomous truck highway journey
http://www.greencarcongress.com/2018/08/20180824-hyundai.html

. . . Hyundai’s Xcient truck drove approximately 40 km (25 miles) on the highway between Uiwang and Incheon, carrying a large semi-trailer simulating cargo transportation.

    This successful demonstration proves that innovative autonomous driving technology can be used to transform the trade logistics industry. At this stage, a human driver is still used to control the vehicle manually in certain situations, but I think we will achieve level 4 automation soon as we are constantly upgrading our technological capability.

    —Maik Ziegler, Ph.D., Director of Commercial Vehicle R&D Strategy Group at Hyundai Motor Company

The demonstration, which took place on 21 August, was conducted using Hyundai’s Xcient model truck, which has a maximum load capacity of 40 tons. This was semi-equipped with a Society of Automotive Engineers (SAE) standard Level 3 autonomous driving system, enabling it to steer, accelerate or decelerate, and maneuver through traffic, all without human input. A human driver was on-board to take over manual control when required.

The vehicle was equipped with innovative technology features, which enabled it to maintain and change lanes during the natural flow of traffic, detect lane changes made by vehicles in front of it, navigate through tunnels, and perform a complete halt or accelerate according to road traffic. . . .

The test route is Hyundai Glovis’s parts transportation most frequently travelled section for vehicles heading to the Port of Incheon. This includes 40km in total of automobile highway. The truck successfully completed the journey, travelling 40km in 1 hour, while abiding strictly to the expressway speed limit of 90 km/h (56 mph).

Hyundai Motor is planning to undertake further autonomous navigation technology tests in future in a variety of areas like Busan, and plans to concentrate on its enterprise development capabilities with the aim of early commercialization of the technology.

Expressways headed toward the Port of Incheon display heavy traffic even during weekdays, due to a high quantity of goods being exported. Therefore the vehicle’s autonomous technology and know-how had to be sufficient enough to adapt to unprecedented situations throughout the journey. . . .

10 different sensors, including 3 front and side-rear cameras, 2 frontal and rear radars, 3 Lidars in the front and sides, and a hitch angle sensor in the trailer coupler which computes the change in angle between the truck and trailer in real-time, allowing the truck to be safely stabilized upon sharp turns.

The data collected by each sensor collaborates with the HD map and sends information to the electronic control module for localization. The module makes accurate decisions for each situation, controlling the speed, steering, and breaking accordingly. . . .

https://www.theverge.com/2018/8/21/1776 ... management was interesting. It linked to some interesting stuff like the below (not sure if it's been pointed to already in this thread):
https://www.theverge.com/2018/5/9/17307 ... -interview had a pointer to a semi-funny Waymo-related video at https://twitter.com/nitguptaa/status/990683818825736192
https://www.theverge.com/2017/10/31/165 ... tle-google

One of the articles points to https://www.theinformation.com/articles ... iving-cars but unfortunately, it's sorta behind a paywall. You can enter an email address to read it. The article has a lot of interesting corner cases and limitations supposedly of Cruise Automation's efforts as of March 2018 that I wasn't aware of.

It also had a sobering section near the end:
‘90-90’ Rule

Cruise, like many other developers, is trying to follow Google. Google began its self-driving car project in 2009, and by 2010 had successfully driven autonomously through 10 separate 100-mile loops in California, across urban streets and highways. In early 2017, Google spun out the venture as Waymo, a separate unit of Google owner Alphabet, after making slow progress in commercializing the technology.

Waymo has an explanation for that: “When you’re 90% done you still have 90% to go,” said Sacha Arnoud, a director of engineering at Waymo, in a recent talk at the Massachusetts Institute of Technology. In other words, writing the first 90% of the code that’s necessary for self-driving cars to function in the real world takes just 10% of the time. Completing the job, or the last 10%, requires 10 times the initial effort.

“You need to 10x the capabilities of your technology. You need to 10x your team size, including finding effective ways for more engineers and more researchers to collaborate together. You need to 10x the capabilities of your sensors. You need to 10x the fundamentally the overall quality of the system, and your testing practices,” he said.

Also, not sure if these have been posted before:
https://www.cnbc.com/2018/05/14/alphabe ... -cars.html
https://www.recode.net/2017/10/15/16472 ... -accidents

These obviously will have implications when self-driving cars are driving around w/no occupants.

I've been seeing both Waymo and Uber autonomous vehicles in my city recently, several times each in the past couple of weeks. I don't know if they're just being used to generate high-def LIDAR maps for now, or if they're actually being driven autonomously; they do have humans behind the wheel. As this is outside of Silicon Valley, I guess they're getting ready to expand outwards.
