In the early 2000s, I had developed via trial-and-error a very convoluted typical route home, cutting through some neighborhoods to bypass interchanges that were typically heavily backed-up during the evening rush hour. It would shave 10 minutes minimum, and sometimes 15-20.

Shortly after 2010, that route became much less useful [due to heavily increased traffic] and when a colleague told me that I should try Waze, I realized that Waze was now sending a bunch of traffic down "my" route home.
