This will be the most middle aged thing I ever post, but:

I'm Gen X. I feel like my generation, and maybe some millennials, got the best of both worlds. We know what it's like to live in an offline world, including cars. You can drop me anywhere in the continental US and I can drive home without GPS, and probably without a map. We grew up on mixtape-fueled road trips and not having every inch of our commute planned and cross-checked. We didn't know exactly what to expect in that upcoming town or city, because there was no Tripadvisor or Wikitravel.

We also know how convenient smartphones can be. It's great that I don't have to carry a camera plus a camcorder plus a Walkman plus an atlas plus a photo album plus a laptop plus a calling card plus a bag phone plus a notepad plus an encyclopedia plus a wristwatch plus a travel alarm clock plus whatever else I'm forgetting. But take that all away, and it's at worst a mild annoyance.

So if I can't use Android Auto, I'm just going to not buy that car. And if all cars suddenly stop shipping with Android Auto, then I'll see that as a precursor to mandatory 30-second ads before being able to drive, and I'll just buy whatever car remotely meets my needs AND makes it easy for me to install an aftermarket Android head unit.
