I'm not going buy that. However, I do believe built-in car GPS totally sucks and except for getting quick directions home, way to time consuming to setup. THEREFORE, I think car GPS is more accurately describes as tech from 10 years ago.
That said, Apple Car Play with Waze is a vast improvement.
I will admit that while Apple Maps has greatly improved from previous iterations, having Google Maps and Waze along with Apple Maps provides a great flexibility of traveling options.
Additionally, in general defense of CarPlay, it might seem like an inconsequential feature, but it will automatically save where you parked your car once you disconnect CarPlay from your car, therefore making sure you don't lose your car... especially once you walk 10 or 12 blocks away in a downtown area.
