Planes with pilots in them are mostly autonomous and can avoid each other as well as the ground.

Yes, mostly.

I wouldn't get on a Russia autonomous flight for a million dollars. Between the corruption, hackey engineering, and complete disregard for safety standards, Russian accidents surprise no one. The Tu-154 accident list is long and scary. Hell, look at all the fires that broke out.

Automated, yes. Autonomous, no. The plane voices an alert, but the pilots still have to react to it.

I meant autonomous with respect to the ground.
