Tesla Motors Club

If I remember correctly, it took at least a year for AP2 to catch up and pass AP1 — and arguably it still hasn’t in a few ways like reading speed limit signs and lane merges. While I imagine much of the AP1 to AP2 situation was because Tesla was moving from an outside vendor to internal development, I would think swapping out the current software for a total rewrite will cause similar issues. I don’t recall Musk addressing this question. Your thoughts?
