The LS also shows of the direction of Lexus design.The newest iteration of the Lexus luxury flagship, the 2018 LS, is on the stand at the 2017 Tokyo Motor Show, but it is also joined by a high-tech version. The Lexus LS is a concept that represents a lofty goal: to eventually eliminate traffic casualties. To help do that, the LS is equipped with "Highway Teammate" automated driving technologies that preview what is to come in consumer cars in 2020. "Highway Teammate" tech allows the LS to drive under its own control on restricted access (motor-vehicle-only) roadways. It can take over driving duties from entrance ramp to exit ramp, says Lexus, including merging and lane changes. The tech also keeps the car in its lane, and maintains an appropriate following distance behind other vehicles, similar to today's lane-keeping assistance and adaptive cruise control functions.
