"As someone driving, you should never drive faster than what you can see ahead and be able to stop in time. I kind of imagine what I'd like to call a "meteor" incident. Would I be able to stop in time if a meteor randomly crashed just outside of my vision ahead in a turn? If not - probably going too fast."
Seems like you've ignored what I just wrote in the previous comment. If I make a turn just as a car is barely out of sight, then at 40 mph there is just enough time to go before it hits me, assuming my car doesn't stall or something. If it is going much faster, say 80, then there would not be enough time. If I have no model of other drivers, and assume anything can happen outside my vision, which is what you seem to be expressing by the word "meteor" then there is no way I can make a turn in either direction safely at all, ever. The only way a person can deal with everyday situations is to assume roughly "normal" behavior (both in a social sense and in terms of physical law) and act accordingly.
In this case, you're the meteor and the other person is at fault. They turned a corner (I don't see how else they couldn't see the intersection - if it's a straight then they can see the intersection - thus my cornering talk) and went into an intersection where another car was already. It's no different than someone romping over a very steep hill (very prevalent in SF) and assuming the intersection they're running into is "clear". (It usually isn't!) It's not a thing they can do and they shouldn't do it.
Either way - sounds like a bad intersection and they should design it differently. (Turn on left with left arrow only, etc.)
"In this case, you're the meteor and the other person is at fault."
Ah, but I'm not. There's a lot of people who live in the same place I do, and they all have to come out of that road in the morning. It's very predictable, not like being hit by a meteor which billions of people have no experience with.
People can and should plan for people turning out of side streets.
A "meteor" would be a car making a turn and stalling right at that moment. Wanting to eliminate that sort of risk is probably related to the problems people are having developing software for self-driving cars.
