had a chance to test drive the Tesla Model S in Australia.

Software update 7.0 adds Autopilot on most cars with hardware capability, provided you pay for it ($2,500 in the U.S.).

That's a lot, but than you get access to pretty unique features of Autosteer - semi-autonomous driving or more like assisted driving, because the driver should be ready to take control at any time.

"Autopilot Convenience Features

Autopilot allows Model S to steer within a lane, change lanes with the simple tap of a turn signal, and manage speed by using active, traffic-aware cruise control. Your car can also scan for a parking space, alert you when one is available, and parallel park on command."
