Honestly, I feel like they’ve made side loading easier and easier as times go on. Used to be that you’d just get a pop up that installs weren’t authorized for that app, then you had to dig through the settings to enable it. Nowadays the pop up has a shortcut to the correct settings page and even visually flashes the right toggle for you to make it easier to find.

I would actually argue that Google Play Music was the best music streaming app that I’ve used. It was great being able to upload music from CDs of small local bands and have it right in there with the other streaming music.

Just today I had a hankering to listen to a specific song through my android auto, and instead of just being able to verbally ask the unit for that song, or even being able to search through the atrocity that is the YouTube Music interface on my head unit, I had to pull over, pull out my phone, search for the band, then click the uploads tab (because uploaded music does not show with the regular search results) and then click the song to get it to play.

I think a skills-based aptitude test that is honed towards specific occupations and a vague intelligence test that the creators even believe barely gives a tenuous grasp on mental ability is not a good comparison.

It’s not a 100% solution, but many head units will have hdmi input, but you might have to accidentally install the head unit in a way that bypasses the parking brake interlock for it to work while driving. Most phones can utilize a USB-C to hdmi adapter for screen mirroring, although touch data won’t be sent to the phone.
