Thanks, this is super helpful! I had never thought of a bluetooth car remote, but it does look like it could be a good solution. I'm actually thinking of upgrading my AirPods to the 2nd gen, which offers built-in controls and would reduce my reliance on the watch's controls.

Do you have any concerns about location data or other data being sent off to China? I had thought it would be enough to forbid the mobile app from having my exact GPS location, but I later realized the watch has GPS and can report that to the app, which can then send it anywhere. I don't know how carefully Apple looks after private data that is collected by a peripheral device.
