I worked for a delivery company in the Bay Area at two different times and the first time I had to learn every street of two cities, and the second time I was provided with printed out turn by turn directions for another city. The 'knowledge' part was horrible to learn but I eventually enjoyed knowing it (during my time with the company), while the printed GPS part was easy to use the whole time. So the question becomes is there a reason nowadays to learn the 'knowledge' part by heart? Not really. It's nice to know while you need it but is otherwise quite useless information because it doesn't teach you anything.
