Automatically Detect Vehicle When Using CarPlay / AA

For folks who switch vehicles often, it seems like it would be a very nice feature to have the vehicle detected automatically. I think this could be done with CarPlay and Android Auto by looking at the MAC address on the other side of the link. Or perhaps it could be done by looking at the data on the ODB2 port.

If this was possible it would both be a convenience and it would prevent “contaminating” the vehicle calibration by making trips in the “wrong” vehicle.
