Hi, just want to know if and how this scenario works. I've got 2 adapters, and 2 cars. My wife and I sometimes switch cars. Right now I have the automatic app on my phone and and the first adapter installed in the car I drive most of the time. On Monday I'll be getting the 2nd adapter to go in the car my wife drives most of the time. Can we have both cars added to the apps on both our phones? Will that work, and what happens if we both get in one of the cars and take a drive together?
