US probes Tesla's Full Self-Driving software after fatal crash

Lots of people are asking how good the self driving has to be before we tolerate it. I got a one month free trial of FSD and turned it off after two weeks. Quite simply: it's dangerous.

- It failed with a cryptic system error while driving

- It started making a left turn far too early that would have scraped the left side of the car on a sign. I had to manually intervene.

- In my opinion, the default setting accelerates way too aggressively. I'd call myself a fairly aggressive driver and it is too aggressive for my taste.

- It tried to make way too many right turns on red when it wasn't safe to. It would creep into the road, almost into the path of oncoming vehicles.

- It didn't merge left to make room for vehicles merging onto the highway. The vehicles then tried to cut in. The system should have avoided an unsafe situation like this in the first place.

- It would switch lanes to go faster on the highway, but then missed an exit on at least one occasion because it couldn't make it back into the right lane in time. Stupid.

After the system error, I lost all trust in FSD from Tesla. Until I ride in one and feel safe, I can't have any faith that this is a reasonable system. Hell, even autopilot does dumb shit on a regular basis. I'm grateful to be getting a car from another manufacturer this year.

The thing that doesn't make sense is the numbers. If it is dangerous in your anecdotes, why don't the reported numbers show more accidents when FSD is on?

When I did the trial on my Tesla, I also noted these kinds of things and felt like I had to take control.

But at the end of the day, only the numbers matter.

Even if it is true that the data show that with FSD (not Autopilot) enabled, drivers are in fewer crashes, I would be worried about other confounding factors.

For instance, I would assume that drivers are more likely to engage FSD in situations of lower complexity (less traffic, little construction or other impediments, overall lesser traffic flow control complexity, etc.) I also believe that at least initially, Tesla only released FSD to drivers with high safety scores relative to their total driver base, another obvious confounding factor.

Happy to be proven wrong though if you have a link to a recent study that goes through all of this.

Either the system causes less loss of life than a human driver or it doesn’t. The confounding factors don’t matter, as Tesla hasn’t presented a study on the subject. That’s in the future, and all stats that are being gathered right now are just that.
