Turn left ahead – Holistic satnavs

Psychologists employed by satnav giant TomTom have developed a brand new turn-by-turn navigation system, that doesn't require a satellite connection.

The new units will use Holistic Positioning technology. Top-secret algorythms will determine the destinations of other cars based upon drivers thought waves, lock on to vehicles which are likely to be going where you are, and follow them.

Expect to see HPS systems in the shops in time for Christmas 2009.
