The problem is not the Autopilot feature but the way it has been
misleadingly and dangerously marketed.
Musk bragged to the press that
Autopilot was "almost twice as good as a person," certainly sending the
wrong message. His ex-wife posted a YouTube video of her driving while
covering her eyes and dancing around while on Autopilot on a crowded
highway. All this has encouraged
a bunch of other YouTube videos of
people behaving foolishly while on Autopilot.
Even the marketing name "Autopilot" is probably misleading to some
people, who might interpret as "the car drives itself without human assistance".
It should have been more conservatively called
"driver assist" or some such.
In the end their marketing stupidity is probably going to bite them
financially. A dashboard warning doesn't excuse it.
I say this regretfully as a Tesla stockholder.
