20: Computerized Navigator
Believe it or not, driving takes a fair amount of skill and planning if you are going on a road trip. Who wants to be stuck trying to read a giant map when you are driving across the country? This is why early navigation systems were an ideal, welcomed choice for drivers. While early navigation systems were carbon copies of what you’d find in the military, this is not suitable for the average driver.
Navigation systems disappeared for a while and have only recently made a comeback to the automotive industry. Today’s navigation systems are powered off of the same technology that you can find on your smartphone or tablet.
