Update:
I have now installed a real Android radio with 8" display (brand: Xtrons). It is like an Android tablet with integration into the auto electronics (steering wheel remote control, for example).
Vivaldi also works with this, as do all other Android apps. There are no restrictions. (You can activate or deactivate an option that videos must not be viewed while driving.)
BTW: Android Auto is also integrated into this device.
When it comes to Android Automotive OS, it's up to the car manufacturer to decide which apps they want to make available for their customers. As for Vivaldi, we're open to partnerships with various car brands and are constantly working on making Vivaldi available on as many devices as possible. 🙂
@Pesala I like Vivaldi because they make their own browser. If you let others start modifying the code to "suit their needs", then it's not really Vivaldi anymore. Just another browser. And at that point what's the point in Vivaldi being involved, telsa might as well just make their own browser.
