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.

I don't think you're supposed to merge left when people are merging on the highway into your lane- you have right of way. I find even with the right of way many people merging aren't paying attention, but I deal with that by slightly speeding up (so they can see me in front of them).

Just because you have the right of way doesn't mean the correct thing to do is to remain in the lane. If remaining in your lane is likely to make someone else do something reckless, you should have been proactive. Not legally, for the sake of being a good driver.

Can you point to some online documentation that recommends changing lanes in preference to speeding up when a person is merging at too slow a speed? What I'm doing is following CHP guidance in this post: https://www.facebook.com/chpmarin/posts/lets-talk-about-merg... """Finally, if you are the vehicle already traveling in the slow lane, show some common courtesy and do what you can to create a space for the person by slowing down a bit or speeding up if it is safer. """

(you probably misinterpreted what I said. I do sometimes change lanes, even well in advance of a merge I know is prone to problems, if that's the safest and most convenient. What I am saying is the guidance I have read indicates that staying in the same lane is generally safer than changing lanes, and speeding up into an empty space is better for everybody than slowing down, especially because many people who are merging will keep slowing down more and more when the highway driver slows for them)
