> One car length is way more than 15 feet to my mind, probably 40 feet or more depending on speed. A car length is, literally, the length of a car. It does not vary with speed. Exception: https://en.wikipedia.org/wiki/Length_contraction (coming soon in a software update to a Tesla near you)

Sure, but saying this is meaningless when we're actually talking about follow distance. Cars are different lengths. To me, a car length should simply mean the minimum safe _length_ at which to follow the car in front of you.

Exactly; car lengths vary by model, not by velocity.

I get it. You'd prefer to use the phrase "car length" to not literally mean "length of a car" in this context. Apologies if I seemed pedantic but, as evidenced by this thread, your use of car length is going against the grain.

Safe following distance is often expressed in multiples of car length. What car? Sure, good point. Pick one; it's close enough! (If you're actually thinking about following distance in any terms at all, even roughly estimated, you're ahead of the safety curve and you clearly are!)

Ideally, following distance could be accurately estimated in metres and adjusted continuously by velocity and driving conditions. AI can do that. People just kind of eye it and say, "it was raining and I followed about four car lengths behind him" or "we were inching along and I was half a car length behind him". Good enough for meat brains!

Safe driving!

Why is this downvoted? This desire to be in control of a car, or the belief one should be in control of a car, is a true curse on the public realm. People who actively think of themselves of good drivers, are invariable the ones who drive aggressively. It's never the ones that drive slow, boring, and predictable that reject safety measures. For example; seatbelts were fought, the fetishization of things like accelera…

The more boring driving is, the more likely i am to look at my phone or fall asleep, find other distractions. If I drive aggressively then i must stay focused. It wouldn't surprise me if these safety features end up increasing collisions because people start feeling safe that the blockchain ai machine learning sensors of the future will do all the work for them. We already see this happening with teslas.

That's a common false sentiment. People driving slower, in a safer cars cause less accidents, less deaths, and they themself die less.

On the other hand a lot of "aggressive" drivers slip up earlier or later. The risk is too high.

Also, looking at a phone is entirely your choice, not a boredom/distraction moment. Listen to audiobooks if your mind needs to do something while driving.

>It wouldn't surprise me if these safety features end up increasing collisions because people start feeling safe that the blockchain ai machine learning sensors of the future will do all the work for them.

I'm all for them but properly tested and validated, not the tesla cowboy approach that musk espouses. I fear that he will discredit the idea before we have serious autonomous driving products.

All I can think about is that poll showing that 90% of people think of themselves as above-average drivers. The autobraking isn't getting in your way and you don't need it, it's exactly for you lmao.

Lol, my jeep that auto-brakes for parked cars in garages. Tell me again what I'm doing wrong by going 5mph in a parking garage?

I'm not here to defend every occurrence of an automated system firing. I'm pointing out that people who think they are attentive and skilled enough to not need these aids are exactly the people who should be using them.

I just bought a 2023 Crosstrek and haven't really noticed it kicking on too aggressively, it does beep sometimes. The only time I get annoyed is when its in adaptive cruise control and someone is merging off the highway it will think they are slowing a lot but its clear they will be out of the way.

Same experience. ACC doesn't brake anywhere near as hard as the emergency auto-brake, but when ACC is enabled and the car in front flips their blinker on and starts moving, I have to proactively feather the gas, otherwise ACC will ride the brakes until they have completely exited the lane. Past that, ACC is a godsend, should be standard everywhere. Lane keep assist also works impressively well (the proactive one that…

ACC was the primary reason I got a new car, and the used market was irrational.

Implementation matters. The automatic braking on my compact SUV has falsely triggered hundreds of times over the course of 3 years, usually when transitioning from a moderately-pitched-down driveway into a roadway. The result of this scenario is the car coming to a dead stop with its front end halfway into a traffic lane, putting me and my passengers at greater risk of a collision from oncoming traffic approaching fr…

Toyota has a good one: it gives me a beep and turns the screen red, but I have to start braking by myself, at which point it takes over and adjusts braking force so as to not hit whatever is in front of me. False positives usually happen when there are cars parked along a turn, but I ignore this completely. Over the course of the five years I had this car it prevented a collision twice this way.

> Toyota has a good one: it gives me a beep and turns the screen red, but I have to start braking by myself, at which point it takes over and adjusts braking force so as to not hit whatever is in front of me.

This way takes away the biggest advantage of this systems - that they can react before you do.

Anecdote here: 2015 Chevrolet SS was slightly aggressive, but overall I'd say tuned extremely well and saved me once when someone drove through a stop sign without looking onto my freeway offramp and then stopped dead. I was already on the brakes but it went into full panic stop a touch faster than I would have and that made the difference. A few times I noticed it preapplying the brakes when someone cut me off, but it never kicked them in during those situations.

Side note, that car has astoundingly good brakes.

>So sure - the guy in front of you may have been extremely reckless, but no one involved is even going to want to hear that narrative. Nobody cares about talk. Everybody lies when they have financial motive to do so and everyone who deals with accidents professionally knows this.

Once again: No! Not for rear ends. For other accidents, yes - I've found they want to listen. Rear ending: Not really: They just want to know who was driving the car that rear ended the other car. I got rear ended once. I spoke to the other party's insurance. Trust me - they didn't want to know why I had gotten hit. It's to their benefit to know, but for them it was an open and shut case. All they wanted to confirm w…

It isn't as black and white as you make it out to be.

I have a dashcam, if someone cuts me off and slams on their brakes I may not have time to react. The party in front could be responsible if you can prove it with a video. The insurance company WILL CARE if you have footage.

However, if someone seems to brake no reason, it is on the driver behind to stop.

Fair enough. I don't believe I fall into that category though, it's not so much that I consider myself skilled enough that the safety system isn't necessary, but rather that I wish I could adjust sensitivity, because I like the idea of the system in general. In this vehicle I'm only able to disable it entirely (which seems unsafe to do, so I keep it on).

Ideally I'd like to have it disabled only when reversing. Between the backup camera, mirrors, and the rear window, the safety systems are already present. The rear bumper really does not need to be triggering emergency brakes imo.

The front bumper though - yeah that one should probably stay on, even if it annoys me sometimes.

Honestly, I feel like a lot of the people complaining about this feature are just bad drivers who regularly drive unsafely and are now getting called out on it.

"And I'm 100% in favor of systems that force other drivers on the road to drive more safely as well." Ug. I'd rather have testing be changed so that safety is increased in all situations by having a competent driver. Most of the situations being described here are simply poor choices on the part of one or more drivers. For real, who the hell is cutting through lanes of traffic and slamming on brakes because they will…

>Ug. I'd rather have testing be changed so that safety is increased in all situations by having a competent driver.

This follows to taking driving license from them.

You'd have to change USA more than Lincoln and Roosevelt together to remove critical dependency on cars there.

I've never had a false alarm from the system on my car. But then, I actually follow the recommended minimum following distances and generally drive safely.

Well, it is either your superior driving behaviors, your car manufacturer's superior implementation, or just the way statistics work that not everyone sees every bug. My car auto-brakes at 5mph for parked cars that are backed into spaces, which I am sure reflects poorly on my driving in some way, if we're adopting the "bad things only happen to bad people" model.
