Apple CarPlay 100% supports Google Maps natively. Waze too if you're into that.

I don't expect it will ever allow casting or playing of videos, even if the vehicle is stopped/parked. Too much liability.

All these improvements to Apple Car Play is utter and total nonsense. The app does nothing more than mimicking a few minor functions that are of little value to the motorist. 

I use Google Maps and Google Search. If I am planning a destination I simply go to Google Search, find the location, then click on directions which then get cast to the head screen and I get there quickly, efficiently and safely. 
I will never, ever use Apple Car Play not since the fiasco with Apple Maps when motorists where directed off the road to an embankment then to an airport in front of airplanes. Apple Maps is like Microsoft Bing never, ever to be used or trusted. 

The only thing that will ever improve my experience and make me consider even looking at Apple Car Play is if they introduce casting. That means that if I am watching the news or any other program while I am driving I can occasionally glance at the screen when it safe to do so and then continue driving. 

When I had an Android Pixel Phone I could do that. The reason that I replaced it with an iPhone is because of security. Android is bug ridden everyone knows that. 

That said there is no reason why Apple cannot add a feature to Apple Car Play to distinguish it from Google Car Play in order to let the motorist cast the phone screen to the head screen. Not minor, silly functionality. 

Incidentally Google Car Play does not do that of itself. You have to root the phone.

Apple has continued to make everything more and more difficult to manage their product.  Removing delta and combo updaters that people used to manage their Macs makes no sense.  So now you have download a full 12GB installer and wait an hour to do a re-install if you are troubleshooting something strange?

The worst was the introduction of the T2 chip which by default prohibits you from installing macOS on your own system, without jumping through hoops (when you want to do a clean-install).  The default is to only allow a macOS install from the Command-R recovery mode, requiring a long download.  By default, you cannot boot from any external drive, unless you specifically disable the restriction that prohibits external drives.  Also, you have to allow macOS install from any source.  If you do not change those settings and you wipe the drive to re-install from an external USB boot disk, you can brick your Mac if you do not have internet access to re-install macOS.

Also, the creator of Diskmaker X has 'retired' the product because he does not have the time to re-write the program to figure out how to make a Big Sur boot disk with all of Apple's changes.  He never could get it to work running Catalina.  So the only way to make a Catalina boot disk is to run it from Mojave.  So I am guessing it is nearly impossible to make a USB boot disk of Big Sur.
