The company, Navigation Technologies, is decidedly low-tech in its approach to making its maps: two people in a car drive around endlessly, inputting street information and landmarks into databases. Navtech's map databases are used in everything from Garmin GPS units to Alpine in-dash auto navigation systems. So next time you turn the wrong way down a one-way street, know that there are real people behind the controls."
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
