The main point of wireless AA and ACP is being able to use the phone for navigation, music, etc. without having to pull it out of one’s pocket, useful for shorter trips. But I see it as a minor inconvenience. I’m trying to get my wife used to using navigation for commuting in order to bypass traffic, and I tell her she needs to let the oil flow for 30-60 seconds before creeping down the alley, so in that period of time, we can plug our phones in and set navigation.
