There's MUCH better than just that! Get a copy of AAAD: https://github.com/shmykelsa/AAAD

That will allow you to install all sorts of "fun" apps Google frowns upon. My car has a 12.1" 1080p screen, but it's not a touchscreen, so I used AAAD to install Screen2Auto, which clones my phone's screen onto my car's screen. I use Bluetooth keyboard ( ) to do any major typing/etc. It fits nicely between the driver's seat and center console, and I put a rubber band around the top of it for grip so it doesn't go sliding when it's on my lap.

/rant: I'm frustrated with Google's heavy-handedness over what Android Auto will display. Just this past weekend I had RadarScope displaying on my car's screen as we were trying to avoid tornadoes from Hurricane Debby. Google thinks users shouldn't have access to on-screen weather while driving. Screen2Auto fixes that. Similarly, I can pull up FlightRadar24, FlightAware, Windy, and even YouTube on-screen with this arrangement, which makes lectures MUCH better-suited for car use.

Take a look at Carstream and Fermata Auto. AAAD will install both of them for you and get them working with just a click. I believe those DO allow touch-screen input on Android apps.
