What do audiophiles do in their cars?

All of you forum members with your killer home systems…what do you listen to in your cars?  Do y’all have custom stereo systems?  Does the quality of the stereo system actually impact your car buying decision?  I have a B&O setup in my 2021 truck, which was an upgrade and sounds decent enough, but nothing compared to a typical HiFi home system.
I have an Acura 2009 which came with a Elliot Schiener/Panasonic 5.1 DVD Audio player.  When I got the car in 2009, DVD-Audio's were already out of print. However, I was able to buy around 30 oop DVD-Audio discs from Ebay, Amazon and other music sites - as well as burn a ton of 5.1 discs. 

The better discs like Hotel California, Rumors were recorded at194 khz/24 bit even back then. To this day, I feel that the sound in my Acura is better than the analog sound from the system I have at home, which is not too shabby. For the first few years, I was really into my car stereo and the 5.1 sound. But like everything else, it got old. I'm more into 2-channel now, but I still have all my 5.1 discs (< 100) and will occasionally listen to it in the car, especially during longer trips.

XM radio on that sweet, sweet Hyundai stereo system. Occasionally I turn that off and listen to the rattle somewhere in the passenger seat frame.
I have always believed that what one "does in one's car", however disgusting, perverse, illegal, or jaw-dropping weird, is one's own damn business.
