Toyota won't be using Android Auto in its US vehicles, favors its own system

According to the New York Times:

John Hanson, the national manager of Toyota's advanced technology communications, said while the company talked frequently with both Google and Apple, it currently had no plans to adopt Android Auto or CarPlay in the United States. "We may all eventually wind up there, but right now we prefer to use our in-house proprietary platforms for those kinds of functions," Mr. Hanson said.
