Not if the sub-optimal routes happen only intermittently and the extent to which they’re sub-optimal (or whether they’re sub-optimal at all) is difficult to determine. If you take the same route every day you’ll notice when it changes, but who are you to say a one-time detour wasn’t the right decision given what you don’t know about traffic conditions?
