The new green cross code

A new sat nav system that finds the greenest route to a destination has been tested in Sweeden, according to New Scientist.

In early tests the device achieved fuel savings of around 8% compared with the normal journey, by taking account of the speed limit and the typical traffic flow amongst other variables.

With few people ever likely to invest in alternative fuel, the project pioneers at the Lund Institute of Technology should be commended for their efforts.

But I’m still waiting for the next generation of sat nav. The dashboard gadget that can tell you which route to take to avoid road rage.
