Most people with old car stereos these days use Bluetooth FM transcievers, I can’t imagine having to burn CDs and then fiddle with them while driving in 2024. It makes more sense to use physical media at home but in the car? I really don’t see the point.

The slower the burn speed, the better. Less chances of error. Aside from that discs are kind of pointless in 2024 when you can have much cheaper, smaller and easier to use flash storage.

Unless maybe you’re archiving something on special, heavy duty DVDs, otherwise why bother?
