Earlier this week Steve Cropley described his experience of automated driving in a Nissan Leaf on urban roads; Toyota is showcasing its own system on motorways, where the company’s customer research suggests drivers will have a strong desire to let the car do the work.

Today I got to ride shotgun with a Toyota driver and experience the system, which the manufacturer is calling ‘Mobility Teammate Concept’. It’s a moderate approach to autonomous driving, with Toyota’s vision being that driver and systems work together in controlling the vehicle.

The white Lexus GS I’m riding in has extra external sensors installed to provide a 360-degree picture of its surroundings and other vehicles, as well as a host of electronic equipment filling the boot.

Our journey starts in ‘manual driving mode’. From the passenger seat I can see that it says as much on the infotainment screen, which is configured to display a special screen of information related to automated driving. It gives the driver details of the surrounding vehicles and roads, warnings about any potential hazards and a display of the steering and pedal inputs being made by the automated driving system.

We head out towards Tokyo’s Shuto Expressway. Once the Lexus goes through a tollgate and up a slip road to the expressway, the system is satisfied that conditions for permitting autonomous driving are fulfilled.
