We've recently seen plenty of developments in both Japanese car satellite navigation systems and the country's earthquake-survival technology . So it's only natural that the two should be combined by some enterprising manufacturer.
Weather data too
The Internavi deck is equipped to receive - via the owner's mobile phone - data about the effects of any tremors in the area. It combines this with existing maps in its memory to show which roads are reported damaged or closed.
In Japan, designated major roads are always closed after a large 'quake so they can be used by the emergency services. The level of detail provided by Honda has also been improved to show information for individual lanes.
Data, based on weather forecasts, about possible flooding is also included in the service. The system will appear in Honda's Fit model late this year at no extra charge, although there are network charges for data packets received.
