Honestly AP2 is pretty damn good on highways right now. Its not L3 but its not hard to imagine that with 5 more months they'd have confidence in you reading and otherwise being awake but not needing to pay attention (no nags!!). Highways are fairly straight-forward and Tesla vision definitely sees far ahead now. With better object and path recognition it will be L3. Tesla might even be building HD maps to further give confidence in positioning.
Even
@Bladerskb has said that highways are easy. That's why
@Bladerskb believes Elon chose the CA to NY route (very little local driving) for the FSD demo but if Tesla is able to do that, even if its easy, its a game changer.
Forget Audi doing 37mph. That's useless other than for urban commuters and they should be looking at a Tesla anyways because AP2 in low speeds (and AP1 too) doesn't nag that much anyways right now.
