ETA

The latest in-car navigation system will promote green driving by telling the driver when to change gear to maximise fuel economy and chastising the motorist who drives erratically, prompting some to dub it a ‘sat nag’ rather than a sat nav.

Vehicles equipped with video cameras, GPS and gyroscopes are currently building the three-dimensional map of British roads that will form the basis of the Advanced Driver Assistance System (ADAS).

The ADAS sat nav will give users a three-dimensional view of the road, including obstacles and road width. It is hoped that the system, which will be in shops within three years, will help prevent articulated lorries getting stuck in narrow country lanes.

Crash-proof cars

A spokesperson for the Environmental Transport Association (ETA) said: “This technology may mark a step towards a car of the future that will not allow itself to be driven badly.”

Mazda has developed an early warning system, which applies the brakes early if it decides a crash is unavoidable, and is able to assess road conditions itself.
