    I drive AP at full attention to the road. And should have been more wary of this truck, for sure.To your point, I don't think we would have made it out by punching it once the truck started to move over.

    When the truck began to encroach my foot moved to the brake, which already engaged fully engaged - assuming by AP, maybe just AEB? We went from about 75 to 30mph in less than a second. One hand went to the horn, and the other to try to split the difference between the concrete and the truck. AP dialed it so quick and so precisely, I didn't have anything better to add to the control. That's my memory.

    I wish I had been more cautious around this truck. I assumed we were within his sight lines because we were overtaking from 100+ ft behind. Did not see the useless mirrors on the truck, or lack of signaling. I did not appreciate this driver's stupidity.

    It's not about hindsight. It's about some people putting too much trust in current AP capabilities. Right now it saved you but that doesn't mean by a long shot that it can be trusted in any hairy situations. You got lucky but you can't say that without AP you'd have been off worse. Most likely you'd have been paying more attention to surroundings and get away from the semi way before he actually made his mistake.

    Did you take the video private? It says so now.

    Ahh, good point. So AP essentially made the decision to slow vs speed up before you could react, so at that point you are committed. Plus you had less room to make it out the front (although the driver MIGHT have spotted you and swerved, but no guarantees they were even looking at the road driving like that.)

    Glad you had to opportunity to be just angry with him for his terrible driving vs the alternative.

    OP wasn't cruising along a semi. The semi literally encroached on the OPs lane from 2 lanes away. Most people wouldn't avoid a semi at the instant it comes next to them.

    As for your thoughts on accidents and "paying attention," way to be captain obvious. Most accidents are obvious in hindsight. That's why they're accidents.

    I was getting trolled by some people who claimed to be relatives of the (now out of work) truck driver.

    Here's a new link to the video:

    Maybe. But if I had been in full control, I don't think I could have been on the brake fast enough, and I really don't think I could have escaped the tunnel cleanly without bouncing off either the concrete divider, the truck, or both.

    Also, data point: I've been driving for 26 years and have never been involved in an accident. Knock on wood.

    I'm having the opposite effect. I'm having ghost braking when using cruise control. Today i was going 75 and it slammed on the brakes until I took over at 30 on the highway. Thank GOD no one was behind me as I would have been killed. Everything in my car was in the front or on the windshield. Horrible.

    Unfortunately, this won’t be anything you see in mainstream media if any kind. Just the bad stuff, or issues they used to have that they already solved, but are still coming up.

    I just read an article recently about the issues with the battery packs on 2012 Model S..8 years later, and they’re still talking about that. And the occasional video of someone railing into a semi while not paying any attention.

    When I worked as an engineer on the oil rigs in Africa, it was tough job because a lot of equipment failed, there was huge pressure to get the job done and done right, and there was little by way of backup equipment.

    Lots of fellow engineers would be applauded for saving the day when they got into a bind. I didn't have too many of those atta-boys because I was more prepared than everyone else and avoided getting into binds (I spent more time inventorying my equipment, learning about the equipment inside and out, pre-checking and double-checking equipment, making sure items didn't get damaged in shipping to the rigs, etc).

    AP didn't save your life, it almost killed you.

    And this is the big problem with any self driving aids like AP. AP doesn't know, and will never know, how to drive defensively. It was just keeping a fixed distance from the car in front, and you never should have been there. You got lucky that AP was able to help get you out the bind it put you in for this scenario. Here in Houston, those barriers are rarely lined up properly, and I really doubt AP could have handled one the barriers jutting out. Being lucky that AP didn't happen to kill me is not a win in my book.

    And I thought the biggest risk from Chiquita was slipping on a banana peel.

    I'm glad that truck driver is out of work.

    Next time don't stay on the side of a semi where it would be difficult to see you like that. Estimated 30%+ of accidents are due to sleep deprivation and truckers are more commonly sleep deprived. One accident and you're likely dead. You were both in the wrong.

    Which is well within the realms of AI and we’re decades away from having that in cars.

    Having logged over 350,000 Tesla miles over the last 11 years, I've been in situations like that several times, and in recent years I've encountered some truckers who see a Tesla coming and pretend like they are moving into your lane to trigger an Autopilot response. As such, if I am next to the cab (ahead of the trailer), I accelerate hard to get out of the way, over-riding Autopilot if necessary. While this is not advisable in an ICE car because of throttle lag and slower acceleration, it is the fastest way to get out of danger in a Tesla, and I consider it the safest maneuver for drivers who are consistently generous with following distance (as Autopilot is).
