Google Maps on Android Auto adds an easier 'Add Stop' button

What I really want out of Google Maps is a way to ask about particular alternate routes. I know it will suggest alternates if it thinks those will save time. But I want to be able to ask it "Should I take the Whitestone or the Throgs Neck", evaluate both routes, and tell me which one is better (and by how much). It already knows where I am going after all.

Bonus points if I can teach it what I prefer. So, I want to be able to tell it how much I hate the Cross Bronx, and that it's OK to send me on a different route if it's 15 minutes longer, if it means I am not stuck on that.

I'd like maps not to become fully unresponsive after completing a trip

I use maps to see a 3d view of my location then I 100% disregard anything else it tells me and make my own way there. I'm never in a rush, and I most certainly don't give a damn about efficiencies in arriving somewhere.

That said, I don't care what they add provided the UIs don't change, and the stupid thing does NOT attempt to talk to me.
