    The Insurance Institute for Highway Safety has started releasing results of its Model 3 tests, awarding a “superior” rating for front crash prevention. IIHS evaluates the stopping capabilities of vehicles equipped with autobrake in two tests at 12 and 25 mph on the Vehicle Research Center test track. In each, an engineer drives the vehicle straight...

    Because it was going 60mph not 25, which it what the IIHS tests AEB for.

    That may be an answer to why his question isn't relevant to this discussion (another is that it wasn't a Model 3)... but the question needs to be asked. I own a Model S and from my own experiences, I'm no longer comfortable that the automatic emergency braking will do its job.

    I have the same questions and concern.
    1. How do we know this driver is telling Tesla the truth about the Model 3 being in autopilot?
    2. With all of these short sellers out there making up stuff, & with the knowledge that the Model 3 is the safest car on the road, how do we know he wasn't planning this accident?
    3. Has Tesla looked into the black box yet to see if the car was in autopilot?
    4. We have thousands of accidents in car accidents every day across this country, and yet Tesla gets two accidents in one week, and the short sellers go nuts on-line saying all kinds of unkind and untrue things.
    Tesla needs to get to the bottom of all of this so we can get down to business, with less distractions.

    Ok, first of all it wasn't a Model 3, it was a Model S. Second... because the girl admitted to looking at her phone. She's admitting guilt. I'm pretty sure some irrelevant detail (to the police and to her at the moment) is going to be truth. But also, Tesla can confirm. Finally... it doesn't matter. The car's emergency automatic braking is supposed to be FULL TIME. Auto pilot or not, the car should have slammed on the brakes.

    because that would be crazy conspiracy theory nonsense. And again, it wasn't a 3. Nor do we have "knowledge that the Model 3 is the safest car on the road". You really think it is going to be safer than its larger siblings?
    I'm sure that will be confirmed shortly, if it hasn't already. They're pretty quick to release details usually.
    Well, that is a valid point of why it is getting media play. I'm not concerned at all about the impact on finances. I'm concerned if my car is as safe as I was led to believe. From my own experiences, I think a recent update changed something because there have been MANY cases over the past months where my car doesn't react AT ALL to stopped cars ahead. I've had to stomp on my brakes uncomfortably (I'm paying attention, but I like to see how the AP behaves). It didn't used to be that way. It used to stop briskly, but comfortably, when approaching stopped cars. I have no empirical evidence... but I suspect something changed and we're seeing the consequences of it.

    Active emergency braking SHOULD have engaged the brakes at some point before slamming into that truck. I don't think there's really any spin on that.

    We don't know what she did right before the crash. If she looked up and hit the brakes herself, she would cancel any AEB being applied. In that situation, she may not of been applying full braking power.

    Also, AEB may have fired and reduced her impact speed from 60 to say 40. Therefore it did its job as advertised in the manual.

    True (on your second point. I think your first is wrong, unless Tesla specifically did something stupid just to be different). And if we find out that AEB engaged, then ok... but then TACC didn't. There's really not much excuse and I'm not sure why people try so hard to forgive them for every failure.

    Good! No offense, but that anyone ever got "comfortable" with it at this point was a false sense of security. On numerous occasions it has demonstrated it has a hard time with certain fixed objects. Don't expect it to work. If it does and saves your ass, great. Otherwise, consider yourself on the clock :)

    While that may be wise advice... it again gives Tesla a they-can-do-no-wrong pass. They sold me a car that's safer than cars one third the price... but my much MUCH cheaper car stops.

    I haven't seen anyone mention that her foot could have been resting on the accelerator. I've used the accelerator while in autosteer and TACC but only when I'm watching the road. :eek:

    This possible scenario would have overridden TACC braking and AEB. She should have received an audible alarm but it could have been too late. Tesla should be able to determine what happened.

    Also noted in the blog piece is that the headlights were rated "Acceptable", which is one step below "Good" but is 2 steps above "Poor", which is what the Model S got last year.

    Here's the link to the Model 3"s IIHS test results page: 2018 Tesla Model 3

    A very common scenario.

    I don’t know that she would have gotten an audible alarm if foot on accelerator.

    If she did (vehicle in front icon turns red, tone sounds), it wouldn’t have been but a split second before impact at that speed.

    I just don’t consider my car as even having AEB anymore. It’s not something I can count upon.

    There are plenty of cases in which the car has reduced greatly my opportunity for an accident. Let’s call that “A”.

    However, there are quite a few in which the car either has not or has increased risk and decreased safety. Call that “B”

    Bottom line is that as long as A > B, then it’s worth it to continue using the active and passive Driver Assist features that have been unfortunately mislabeled “autopilot”.

    Except it doesn’t, and isn’t. It’s 0-2 against emergency services vehicles (such as fire trucks).

    Other than that, I’m sure AEB is an Absolutely Fabulous feature.

    I am however, reminded by your post that it is a very good idea to re-read the manual every 6 months or so, and am setting a reminder to that effect now.

    Headlights: I wonder if anyone adjusted the headlights? I found mine to be a bit low so, in Car/Service, I hit the adjust headlights and turned them up a little.

    I agree, but the point is, this is all any manufacturers' vehicles are legally required to do - simply reduce the speed of a frontal collision.

    Pick a car, any car (I chose BMW 3 series in the link below). Select Front Crash Prevention from the left-side menu and the test results are always along the lines of:

    2018 BMW 3 series

    If a car stops in time on the 12 and 25 mph tests, it's awarded a few extra points. If it crashes, it still get points and this model of BMW gained a total of 3 points so apparently it can be classed as having "Advanced" front crash prevention - even though it crashed on the tests!

    How about 50 mph? What about 70 mph? These speeds are not a requirement of the certification process.

    Advanced? How is this Advanced??

    Does Automatic Emergency Braking mean what members of the public assume that it means? Hell no.

    Does this matter? Up until recently, no, not really, because our lack of understanding of AEB isn't exposed in normal driving - we drive, we see things, we brake, most of the time we stop, sometimes we don't. We drive manually and we pay attention.

    With the rise of AP and systems like it, folks are starting to realise that there are a number of driver assist systems which have been around for a while where we haven't bothered/needed to read the fine print.

    There is a legacy of driver assumptions which are now starting to bite back.

    I'm with you 100% on regular manual updates.

    And they really should change the definition of AEB.

    Unless I'm missing something, all you did was quote me twice and added nothing?

    The pictures I did see was of a black car crumpled into a firetruck, I'm not an investigator of accidents, so it looked like a model 3 to me. The article I read was of a model three saying it was listed as one of the best and safest cars on the road, so I assumed that they were referring to that accident or that model car.
    I also read that the driver was a he, because news reported that he broke his right ankle, so if the driver is a Woman, that was reported wrong, no surprise there.

    People will do the say and do strangest things to bring down Tesla, look at what GM did in 1990 when they lied to their leased EV1 car owners when they were told to turn them in so they could upgrade them, but instead they crushed every one of them.
    I realize that has nothing to do with this, I am using it as an example as to what has been done to bring down the idea of electric vehicles, they just don't want the competition.

    With that said the above should make you realize of what could be going on here, we are talking about multi billions of dollars, and these other people invested in the every day ordinary auto are threatened by Tesla, and I might add other EV makers.

    The fact that Tesla is taking it's time to come out with the truth, or at least what the black box will tell them is a good thing.
