I just went over to the Google Maps page and noticed a new feature that said "Drag the blue line to change your route." Curiosity got the best of me so I decided to try it out to see what it did, and after creating a route I noticed that I can make Google Maps go the way I want it to when giving directions. Check it out in this very quick video that I put together:
Pretty cool, huh? I was pretty impressed with what it could do, and the concept is pretty simple. It essentially just adds "way points" to the course to make sure it passes through that location, but it is useful when Google Maps takes you a slightly different route than you would really like to go. Now just drag and drop the blue line until it is perfect in your eyes!
