As Tesla Motors detailed a software update aimed at reducing battery concerns in its Model S, CEO Elon Musk on Thursday announced an "auto steering" feature that should be ready in "about three months."
"We can basically go between San Francisco and Seattle without the driver doing anything," Musk said.
With the technology, drivers would not have to control the steering wheel, acceleration or braking when the car is on a highway. The announcement came during a press conference in which Musk detailed a separate update that includes a "range assurance" application and a trip planner.

The software will warn Model S drivers before they drive out of charging range and plan routes with charging stations, making it "basically impossible" to run out of battery before reaching a station, he added.
