Seems to me that the cars behind the Tesla are the omas at fault?

Note that the Tesla changed lanes, into the passing lane no less, and then immediately slowed down significantly.

So the first car to hit it may have had a very safe distance between it in the next car, but the Tesla cut that significantly with its sudden maneuver.

They are of course at fault for not leaving a safe distance. But ultimately the behaviour of the Tesla FSD system is what caused the chain of accidents.

> They are of course at fault for not leaving a safe distance.

They weren't following the Tesla. And a reasonable safe distance does not usually account for the guy in front of you doing an assisted stop. That is far enough outside reasonable expectations.

This looks like the vehicle tried and failed to get the driver to engage and pulled over best it could. There is no shoulder there so… Let’s wait to get more info as to what the driver was doing and if they were incapacitated. The FSD beta is pretty aggressive on making sure the driver is paying attention via both steering sensors, the in-cabin camera and the touch screen.

> pulled over best it could

If that is its best then FSD has no business being on the road.

It was erratic and didn't give clear intent to other cars what it was trying to do.

Earlier quoted context omitted.

I would never want that though. It should change lanes and pass.

It’s very useful on long drives since you don’t have to constantly adjust your speed by little bits (manually or adjusting the cruise control setting). Takes a moment to moment mental load off so you can focus on the other cars around you better. If the cars ahead of me are slowing down significantly I disengage and go manual until I have a better idea what’s going on. My car can supposedly stop completely that way.…

I wonder why this is preferable to just taking the train for longer trips? Wouldn't it be nicer to sit back and let someone else do all the driving for however many hundred of you are all going to the same place anyway? Once you get past the long part of the trip you could always rent a car if it's rural or whatever.

The question that is never answered in this kind of story is:

1. How many fatalities per mile does tesla FSD have, compared to its best alternative if we ban it?

2. Focusing on specific failure cases is not relevant since the political decision to allow it is all or nothing.

3. It'd be perfectly logical to accept road testing FSD, even if it's significantly worse in some areas, as long as this is not exploitable, AND the net gain from allowing it is still overall positive.

I'd like to hear reasonable disagreements like "Tesla isn't actually all-in net positive" or "Here's why we should judge policy by something more than just net lives lost/saved".

Edit: the discussion fragments into two versions depending on the state of facts, which isn't clear:

A) Tesla FSD is not actually safer per-mile. If this is the case, I and most people would probably agree not to allow FSD on public roads. That's not really what this is about.

B) Tesla FSD is actually, on net safer per mile, but we should not allow it anyway.

I'm welcome to hear other options, too, but while replying I'd like to hear which one you think.

Don’t you just tap the brake to disengage adaptive cruise?

The problem isn't that disengaging the system is difficult. The problem is that deciding whether to disengage is difficult. If you're catching up to a slower car, maybe you should disengage the cruise control. Or maybe you shouldn't. You can't tell. This means that cruise control goes from being something that relieves stress on you to something that causes additional stress.

Seems like the car should have a UI that says something like "Car ahead is 15km/h slower, I will brake to maintain 50 meters distance between us, current distance: 70 meters, approach speed: 4m/s, will start braking in 3 seconds.", so the driver knows that the computer is aware of what's going on. Use some pretty graphs/animations to make it easier to understand.

I have a VW Golf and it has what it calls "adaptive cruise control". What makes it different from my older (simple) cruise control is that it will slow down and speed up again as necessary without my intervention. For example, if I set the speed to 70 mph and it gets close to a car ahead that is only going 65 mph, it will slow down and maintain what the software believes is a safe distance. Similarly, if a car in an…

My friend was using adaptive cruise control while towing a caravan. A car merged in front of him, his car applied heavy braking to maintain the desired distance (not necessarily to avoid a crash) but didn't compensate for the weight of the caravan. Almost lost traction, lead to heavy swerving. He's vowed to never use it again.

Doesn't his car have ABS? Even under heavy braking, the car's wheels shouldn't lock up and lead to swerving. Did the trailer have its own brakes?

You can see them get out of the vehicle and walk around a bit in the video[0], so I guess they were not incapacitated - see around the 46s mark in the video. The driver also claimed they were using FSD at the time the car performed the maneuver.

As others have pointed out in yesterday's submission. This could have been avoided if the cars behind them were leaving a more defensive distance to the other cars. In all directions, you can't just look ahead, you gotta observe what's going on around you.

I do love the ACC on my car. One of the worst parts of road trips is following cars you don't want to or can't pass. The ACC totally solves it. I don't see how you were really able to use cruise to follow another car at all before? Even 1mph too slow is not great and if the car in front isn't using any cruise control at all it could be 5mph too slow and then 5mph too fast.

In my car without ACC, I just hit the up/down buttons to adjust the speed for the car in front. Not a big deal when there's a small speed difference, but certainly not as convenient as ACC.
