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.

Tesla jumped the gun on the FSD free trial earlier this year. It was nowhere near good enough at the time. Most people who tried it for the first time probably share your opinion.

That said, there is a night and day difference between FSD 12.3 that you experienced earlier this year and the latest version 12.6. It will still make mistakes from time to time but the improvement is massive and obvious. More importantly, the rate of improvement in the past two months has been much faster than before.

Yesterday I spent an hour in the car over three drives and did not have to turn the steering wheel at all except for parking. That never happened on 12.3. And I don't even have 12.6 yet, this is still 12.5; others report that 12.6 is a noticeable improvement over 12.5. And version 13 is scheduled for release in the next two weeks, and the FSD team has actually hit their last few release milestones.

People are right that it is still not ready yet, but if they think it will stay that way forever they are about to be very surprised. At the current rate of improvement it will be quite good within a year and in two or three I could see it actually reaching the point where it could operate unsupervised.

I have yet to see a difference. I let it highway drive for an hour and it cut off a semi, coming within 9 to 12 inches of the bumper for no reason. I heard about that one believe me.

It got stuck in a side street trying to get to a target parking lot, shaking the wheel back and forth.

It's no better so far and this is the first day.

Is it possible you have a lemon? Genuine question. I’ve had nothing but positive experiences with FSD for the last several months and many thousands of miles.
