New Nissan Leafs support both CarPlay and Android Auto, thankfully.
From what I’ve seen most cars that support one support the other. It seems to be rare for a car to only support one of the two. Must be easy to implement both of you do one of them.
Perhaps it was my coming from the crime against humanity that is CarWings in my old Nissan Leaf. I liked my Leaf, but there was nothing on the center console that wasn't better on my iPhone.
