There's more than just Qualcomm in the ARM market.

Also, so what? Do you think the cars are currently sold at a loss? They profit on each car sold, and that includes the infotainment.

You can't run it on a Mediatek or a Rokchip or whatever?

That's such an obvious deflection, though. My last car was a GM vehicle, with built-in OnStar right there in the box behind the rearview mirror. Built into the price I paid was hardware I didn't want, didn't pay a subscription for, yet was collecting my driving data and selling it.

Building a functionally useful infotainment system to replace Android Auto, with all of the bells and whistles needed to complete, is going to cost them the same or more. The difference is the rent seeking behavior, the demand for subscriptions, and getting more opportunities to spy on their customers for profit.
