Car drivers often complain that they feel isolated from their surroundings, unlike their counterparts on motorcycles, for example.
Today’s invention is to connect their in-car entertainment system speakers to a GPS unit and a mobile comms link which will provide a local soundtrack -based on the vehicle’s location (and perhaps also the current weather conditions).
This might involve regional music, snatches of conversation, wildlife noises, wind-in-the-trees, birdsong -anything which could help provide passengers in a car with an experience which is more embedded in the surrounding environment (It probably wouldn’t include enhanced road noise, if you were travelling on a motorway).
This might even have a calming, and slowing, influence on motorists.
