Amazon patent hints at self-driving car plans

Reversible lanes pose problem for autonomous cars and trucks, but Amazon has worked out a possible solution

Amazon is working on self-driving cars, according to a new patent that deals with the complex task of navigating reversible lanes.

The patent, filed in November 2015 and granted on Tuesday, covers the problem of how to deal with reversible lanes, which change direction depending on the bulk of the traffic flow. This type of lane is typically used to manage commuter traffic into and out of cities, particularly in the US.
