I agree. The "autonomous driver" should be expected to ethically mirror a hired driver. You wouldn't knowingly get in a cab whose driver considers himself and his passengers expendable, so why would you be okay with the car doing that?
I've had people make the same argument to me against the WikiLeaks leaks in general, except with the Obama regime instead of the Mugabe one.
That embarrassing a corrupt government is going to lead to a crackdown is no real excuse not to embarrass them, as they're going to find an excuse to crack down either way.
