It boggles my mind that people would continue to use a car that randomly breaks without their input.

I have a 2019 and I've used autopilot extensively and i've never had it break when it shouldn't. I've had it beep at me erroneously maybe twice, so I think this is something in the settings that is causing the issue.

The "settings" might be about where you're driving. Certain locations might be more prone to make AP see things.

Likely the US implicitly sets the standards for other markets since it’s easier to build one platform.

It’s illegal to sell European cars in America and vice versa, without making special versions.

Still, keeping as much the same provides benefits.

I’d be interested in seeing if there statistics of automobile safety in the US before and after Nader, compared to the equivalent statistics in Europe. I have a suspicion that the progression in car safety is a more global phenomenon

Likely the US implicitly sets the standards for other markets since it’s easier to build one platform.

I think it’s the opposite, there are nearly no US models sold in the EU, whereas many EU cars are sold in the US (99% German)

I currently drive a 2021 Rav4 Prime and it's not like that at all. The adaptive cruise control is smooth and never makes mistakes. Lane assistance is helpful but not as close to flawless, mostly due to poorly marked lanes.

was it on flat roads or more challenging terrain? it was apparent that it was a very simple system that did not attempt to do any estimation beyond what was immediately visible to the sensors. so if there was a change in the pitch of the road, it would immediately react as the sensors became occluded and then regained their field of view. maybe in situations that challenging, it should complain and force manual contr…

> so if there was a change in the pitch of the road, it would immediately react as the sensors became occluded and then regained their field of view

I've used it on miles of interstate in the mountains, but that's never a problem because interstates don't change pitch that rapidly (by design).

You must be using it on a very different roads than I do. I only use it on large, US interstates.

I can't imagine a cop anywhere in the world responding well to the phrase "unsurprising because you were following me too closely," especially if s/he already thinks you were brake checking them!

By the time you're fighting the ticket, it doesn't much matter how the cop reacts.

Now you get to add a defense lawyer's trial rate...

Most cars have this starting in 2016. Later this year every single car will be mandated to have automatic emergency braking. At least Tesla will have millions of miles of practice. https://www.consumerreports.org/car-safety/most-new-cars-hav...

Most (all?) other cars have radars for this. They do not seem to experience as many problems as Teslas, which is especially telling considering how much more other cars are on the road.

2022 Model Y with FSD. I use Autopilot 50+ miles a day, and use it 98% of the way on trips from San Diego to SF. It infrequently phantom brakes, and more often brakes hard and late and sometimes people think I'm brake-checking them. It also is annoying slow to recover back to cruise speed from a slow down. Also if you're in the right lane when the two right lanes merge- it is totally unreliable, I've been sandwiched…

2018 Model 3 with Enhanced Autopilot. I took a weekend trip from LA to Phoenix a few months back. I was in the left-most lane for a majority of the trip, and had ~10 phantom braking occurrences each way. It seemed to think the shadow of a car in the adjacent lane (where the shadow fell well into my lane) was something that needed to be avoided. It also doesn't infrequently highlight a car in an adjacent lane (or even…

It surprises me that even after all of tha you still consider using autopilot and seem to have accepted the phantom braking as a way of life.

> What behavior are you referring to? Automatic Emergency Braking. You cannot turn off AEB persistently. > I'm not aware of any feature that requires me to accelerate or brake to prevent the car from stopping itself Before the car emergency brakes, it will warn you via "Forward Collision Warning"; the screen will show the object it thinks you're about to hit in red. You can set this to "Late" to reduce false positive…

This article is about autopilot phantom braking, not AEB. I've never had AEB trigger, or heard of it triggering when it shouldn't, but maybe I'm unaware.

i had it trigger twice: once to prevent a frontal crash that would have been my fault, and once during a storm. i am very glad that it is there; works extremely well.

This is why the law requires people to follow at a safe distance. If you're only leaving room for "instant response times" then you had better have instant response times because you're liable.

The question isn't who's legally liable. The question is are you doing things more unsafely than you need to be. You don't have to be legally at fault to be doing something that's unsafe for other drivers to deal with. Sudden breaking at highway speeds, especially for no actual reason, even if the person behind you is following at a safe distance, is rolling the dice that every car behind you for a while is driving a…

if a car is tailgating me (less than one car length of space behind me above 30 mph), and my Tesla sees a ghost and brakes hard, and the car behind me rams into me, then that is completely on them. it's on me if they were further away than that.
