Ok, I'll play
No it doesn't. At least not necessarily. You can still have effectively completed all your scans and consciously decide to indicate to no one in particular. The argument against it is that it promotes "autopilot" driving, but the argument for it is that auto reflexes such as that are more useful than harmful, particularly for drivers who spend a lot of time in built-up areas where peds can occasionally be hard to see, or may appear unexpectedly.
In 30-odd years I've never seen this argument won by the "don't indicate" side when they're asked to provide a clear scenario of greater benefit than harm.
Your turn!
