It cannot self-propagate to any Android-based head unit
Remember that not that long ago viruses spread through floppy disks.
Today, people share USB sticks full of music from one car to another all the time. They also bring their music from their home car to a rental car and back.
I’ve never met anyone irl who used USB sticks full of music. I know the capability is there in most cars, just never seen it. It seems like Bluetooth capability and Spotify/Apple Music landed in mainstream cars too soon after “play MP3s from USB” was added, for that to catch on.

I've been doing it for years, since it's so much more convenient than the alternatives: plug the stick into my car and I have my whole music library there and it Just Works.
My hand is raised. I like having 8GB of music on an old (USB2 is fine) flash drive in my car as a fallback. On longer trips I'll hookup the Android Auto, but if I don't need maps and it's a quick ride, shuffle & repeat all enabled on the USB source.
Sure beats the radio, which plays 2 songs and then 5 min of commercials/sweepers, and has the gall to run ads on the HD text transmission on FM designed for song information.
Most people just bring their phone between cars for music.
My phone is much clunkier to use for this than a USB stick. Plus my phone can't store my whole music library (because there's too much other stuff already on it), whereas a single USB stick does it easily with plenty of room to spare.
