Anecdotally, I've heard people say they almost got into a crash because of lane assist, especially with the white/yellow temporary lines. But that does depend a ton on the car.
I have to agree that if you have to turn, you should be able to turn, lane assist be damned - we're not yet at the level where a car can accurately judge 100% of the road situations. But it's probably a good thing we're moving into a future where crossing lanes without turn signals feels like a virtual bump on the road.
...I was gonna say it took until it was shrunk down to the thumbnail to see red, but nope, it actually has red in it in the thumbnail.
Guess this is specific to how often you see cans of coca-cola?
Here, I put the image through a ditherer (only available colours are black, cyan, white). I don't see any red at all now.
[edit}
Actually, that "red" is mostly just gray so I played myself here. Still, the luminosity must be closer to red before I detect it as red, white doesn't do it.
