I believe that the Sat-Nav when used correctly is a wonderful aid to road safety.
I can give you a driving lesson on how to use one correctly.
Where on earth?
A history of the Sat-nav
The first satellite navigation system was called Transit and established by the US military in the 60s'.
The idea of offering sat-nav for drivers was first floated
in the mid-80s'. A system called Homer, based around a modified IBM
computer with a screen built into a car's glovebox, was unveiled at a
German trade fair in 1985.
There is debate about which car brand had the first sat-nav
for its owners. The American-market 1990 Honda Legend was certainly one
of the first, using gyroscopes and accelerometers to work out position.
The first portable devices arrived in shops in 1991, and moving maps started two years later.
The sat-nav business exploded in 1994 when America opened up
its military Global Positioning System (GPS) of 32 satellites for
commercial licensing. US car brand Oldsmobile was the first to launch a
GPS system for vehicles, GuideStar, in 1995.
Maps first appeared on mobile phones in 1998 and spoken
route guidance was launched in 2001. Devices aimed specifically at
motorcyclists arrived in 2006.
