Sounds at least plausible. Seems that would be a way to "smooth" out the speed problems to start.Total conspiracy theory here, but what if early v12 was E2E, but subsequent versions are adding back bits of hard code to solve some issues, like the low speed?
Also referencing Chucks ULT. It seems one of the biggest regressions is the inability to pull into the turn lane at an angle and stop (this is at best a legally ambiguous move). For instance this may benefit from hard code. Elon must be steaming after the latest "embarrassing" video. May even put Chuck back on the naughty list.
