Those merge lanes seemed longer and more gradual than many I encounter. Either way, the behavior is certainly not remarkable; a minor quibble at best.
It’s just a post showing that the behavior exhibited on the freeway in merge lanes can occur in some situations with FSD. It’s more notable at higher speeds. And in the video of course it is quite evident too.
I guess looking at the lines is the easiest way to get past the wide angle deception; it is a substantial shift:
So we should not, by default, assume that “single stack will fix it.”
Hopefully it does. They’re still working on incorporating lane markings - we’ll see whether this disappears (in this specific case) in 10.69.3! Should not be necessary to have the arrows but whatever works.
