That's a very odd way of putting it. You do realise that music is not just a marketing platform, but also a very common form of entertainment and medium for artistic expression, right?
I'm not sure if you're saying that you don't listen to music at all while you're driving, but if you are, I think you have a very uncommon experience. When I ride in other people's cars, there is almost always music playing, either from a phone connected over bluetooth, a stack of CDs in a CD changer, or just a music radio station. Driving in silence is so uncommon that I'd consider it strange. When I am driving my own car, I often use my long Australian commute as an opportunity to listen to a full album.
Given that people do listen to music in cars, and that against better advice, they often fiddle with their non-built-in music playback devices while the car is in motion, an in-car entertainment system with a proper interface goes a long way to prevent distracted driving.
However, I have never crossed Australia, in either direction.
Sadly pretty much no longer available in a new car. So I'll probably never buy another one.
I don't use active GPSes, although I do use electronic maps for plotting my route beforehand. I prefer to know where I am going, and I hate the GPSs that try to talk to my with the force of a thousand suns.
I'm soon to be audio free, no auxiliary input on the car's system and FM is being turned off this month in Norway. So, silence from now on aside from the gibbering emanating from my very own pie-hole.
Isn't there also something nice about driving along with only the faint glow of green or blue from the dashboard, not the 46" screen that Tesla have 'tastefully' mounted in the dash?
