Japan Inc. made in-car navigation systems of their own Accord

Good intentions aside, sometimes innovation winds up paving a road straight to the nether regions of unprofitable, unsellable technology. That's a shame, because great ideas aren't necessarily ready for primetime in their initial stages. Iteration is often necessary to really perfect technology, but plenty of promising concepts never got the chance and were left to gather dust.

The early days of Navigation systems were pretty crazy. Almost German in it's complexity!
