I want my child to have as much autonomy as possible early on. Like before the age of 10 if she can ride her bike across town to her friends house or get on a bus to the mall or playground or library, I will be very happy.

Having the ability to see when she's safely off the road, or if she's stopped in a place that seems like it could be an accident could be the difference between me choosing to afford her all that freedom or not. Also, I won't ask her to habitually carry any kind of traffic device without giving here equivalent visibility into my movements.
