"once you learn the quirks"

I had to laugh at this statement - imagine if I had to tell to a patient that he had to learn the quirks of his defib - so it "might" randomly just restart your heart at inopportune times but just hold on while it happens :).

My parents-in-law own a late-model VW. It’s not my car, but I drive it regularly when we visit. Despite limited use, in the last year or so I’ve had 3 phantom braking incidents - one with my son in the car that almost resulted in an actual collision with another vehicle.

I hate this car so much. I cannot believe that VW thinks this junk technology is a good idea and I will never, ever buy a VW.

It's honestly like a black mirror episode. "I have to have maintain a mental model of how my black box ML car AI will act so I don't die or kill other road users... and it can be updated daily."

Autopilot in aircraft have a similar problem, which led to the Air France Flight 447 crash in 2009. The airspeed indicators froze over, the autopilot switched from "normal law" to "alternate law", and the pilots failed to understand that the autopilot's protection from stalling no longer applied. They did not have enough training (or were too confused) to fly without the help of automated aids and flew the plane righ…

Of course, (unlike some commenters in this thread) the air travel industry thankfully had the good sense to look at autopilot on balance rather than fixating on a single fatal accident (or in the case of Tesla's Autopilot, the mere possibility of a fatal accident). The salient question isn't whether or not an autopilot allows for any fatalities, but rather whether or not it reduces fatalities relative to manual piloting/driving.

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…

I'm pretty sure Tesla's with FSD get in less accidents when compared to the average driver. Mine tends to be frustratingly overly cautious in most cases.

Except when it suddenly turns into incoming traffic. Don’t believe stats from Tesla.

> Except when it suddenly turns into incoming traffic

Is there any reason to suggest these aren't factored into the aforementioned data?

> Don’t believe stats from Tesla.

I'm all for more transparency, but I'm certainly not going to trust a random Internet commenter either.

Lol. Tesla is really just beta testing in production. When software companies do that we say it’s bad. When Tesla dies this it’s ground breaking innovation. When my internet browser crashes no one dies.

Sure, but if you're doing it far later than a human would have done it, then you're really screwing with the person behind you who isn't an AI with instant response times.

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 at full attention.

"I require every other human driver to be driving correctly so that my AI-car may drive unsafely" seems like a bad bet. I'd also imagine that, if as a human, I just slammed on my breaks for no reason on the highway, I would be found to be at fault for an accident assuming the car behind me wasn't directly tailgating me.

Not defending Tesla here, but this is exactly how I think of other drivers on the road, whether I'm driving, cycling or walking.

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…

Would you still recommend Tesla after these experiences?

Yep, autopilot is a good helper but a bad master. In the air there's a lot more space and fewer objects to avoid than on the roads, yet nobody has managed to build a perfect autopilot that could really replace pilots in every situation. I remain skeptical that we'll ever see one in any dimension, let it be air, sea or land.
