The driver had his hands off the wheel for all but 51 seconds of the last 14 minutes A/P was engaged, and either had a bagel or a cup of coffee in one hand, plus was distracted by the radio. The report goes into detail about how the A/P warning system works, including the fact that on a divided highway you can go 3 minutes hands-off before a warning is issued, if there is a lead car, and 2 minutes otherwise. The first audible warning is issued 15 seconds after the visual warning, the second 10 seconds after that, and the third 5 seconds later, at which point the car begins to decelerate. In other words, you can go at least (see below) 3 min. 30 seconds with your hands off the wheel before the car will assume no one's paying attention.

The car had hardware v1.0 and firmware 17.50.97-3bd9f6d082U, installed on 12/28/2017. Some of the warning times have apparently changed in later versions of hardware and firmware. The total trip was 66 minutes, and A/P was engaged for a total of 29 min. 4 sec., with hands detected on the wheel for only 78 sec. total. During the last A/P segment, visual hands-off alerts were issued four times,, and no hands were detected for the last 3'41" before impact. This was possible because the car's speed dropped below 25 mph at some point, which allows up to 10 minutes before a warning is issued. The Tesla slowed to 21 mph behind the lead vehicle.

When the lead vehicle changed lanes to avoid the fire truck 3-4 seconds before impact, the Tesla began to accelerate to the TACC set speed of 80 mph (speed limit is 65). At 0.49 sec. before impact the FCW detected a stationary object (the fire engine) and issued audible and visual warnings to the driver. The Tesla was doing 30.9 mph at impact. AEB didn't activate nor would it as it's known that it can't deal with this situation.

To what should be no one's surprise, this is another confirmation that A/P as implemented not only allows but even encourages driver disengagement, just as all the research indicated would be the effect of such an implementation.
Lovely how you're still on your high-horse without any expertise in AI whatsoever.

Isn't it about time for another A/P death? Yet, there hasn't been one since March? Why focus so intently on the accidents that have happened, and NOT on the ones avoided? Those news reports about drivers caught sleeping on A/P were all instances of drivers that could've died if they were in another car. A/P isn't perfect. Focusing on the accidents that have occured is completely missing the point of A/P.

I'd written a long reply to this, but MNL timed me out and made me log-in again, and the reply was gone after I did so. As I lack the patience or interest to re-write it all, this will have to do, which covers some but not all of the points I did:
Feds scold Tesla for slow response on driver monitoring
In 2017, NTSB called steering wheel torque a "poor surrogate" for driver attention.
https://arstechnica.com/cars/2019/09/fe ... onitoring/


Eye-monitoring cameras have proven to be more effective than torque sensors at ensuring drivers remain engaged, and ideally you want to use both systems - Cadillac does so, and so do several other manufacturers.

These are people who may have decided to drive tired and exhausted because they had A/P. Is that safer than not driving? We can certainly be glad that they didn't encounter a stopped vehicle in their lane, as they were apparently traveling at 55-60 mph, unlike many of the other Tesla crashes into non-moving vehicles - the fatal crash in China was moving at high speed. More importantly, IIRR so far no one has been in/on any of the vehicles that A/P-guided Teslas have rear-ended; if a firefighter/police officer/maintenance worker had been in or standing on or behind their stopped vehicle at the time and was injured or killed, would you be so blase' about this? Do you think the public will be? I mean, the occupants decided to do something stupid and thus consented to the risk, but other members of the public haven't given any such consent.

Beyond that, does this and numerous other examples of misusing A/P indicate that the system as implemented does the best possible job of ensuring that the driver remains alert and ready to instantly retake control when needed, given the design options and equipment available to Tesla? Of course it doesn't.

Would drastically shortening the time to the first hands-off warning and the following slow to a stop make drivers keep their hands on the wheel and pay more attention to avoid constant annoying warnings, especially if they were both visual and aural? Sure. Google used 6 seconds for their driver-assist program (before deciding it wasn't worth the effort and going for FSD), but for those companies who do want to offer driver assistance, this is an obvious step, far better than the minutes that Tesla currently allows.

Would adding an eye monitoring camera further increase the chances that a driver will be watching the road instead of watching a movie or sleeping, and oblivious to everything that's going on around them? You bet.

People Are Already Reporting Collisions With Tesla’s Driverless Smart Summon Feature
The functionality is part of Tesla’s V10 software, which had its widespread release earlier this week.

Above has 3 videos.

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

I stumbled across https://jalopnik.com/people-using-tesla ... 1838593877 and wasn't of this tweet w/video: https://twitter.com/Tesla/status/1177301824128393225. It sure does look like it's going the wrong way down a one-way section of the parking lot. If it really is two way, that is really weird given the width and angle the cars are parked at.

Hi Doug, here’s my experience with Summon (singular, plural “summons” is a legal document). Before the Enhanced version’s broad installation over the last few days, Summon worked for me away from my home in situations like moving the car out of a parking spot where someone had parked very close. Just move the car out of the slot either forward or backward one car length...all good. At home however there is some connectivity issue precluding the use of Summon so no joy.

About an hour ago I was treated to an over-the-air update to Tesla’s newest wide release of software, dubbed “V10,” and it included Enhanced Summon. Have not tried it yet either at home or elsewhere, but the Tesla blogs relate pretty impressive stories about how good, and several incidents to show how poorly, it works. Apparently it is very situational, and of course still a Beta feature.

Regardless, it is an amazing next step in the pursuit of driving autonomy. As to whether I like it? What’s not to like? It is optional, i.e., you don’t have to ever use it, and it does work in many scenarios. Certainly a nice convenience in any event.
