In a city not only does it do random things, when it does work it’s calibrated so poorly people behind me signal all the time because it’s too slow.

On a freeway it’s only kind of usable. It switches lanes far too aggressively and for no reason, to the point that it makes the ride uncomfortable.

What I really want is auto steer with lane switching when I signal, which for some reason I could never get working in any mode. It either doesn’t change lanes at all, or changes them arbitrarily of its own volition. And if I change lanes manually it turns off autosteer, which is too irritating to use in practice.

Tesla self driving, in any mode, is a bad product. And I say this as a Tesla fan.
