Well, when you drive almost 100 miles to get to work, it's nice to have an hour and a half of good quality music instead of silence or low-fidelity tinny shit.
Also the passengers in my vehicle appreciate music since they don't have to focus on anything else.
Plus, you know... All the times I've been in my car without driving somewhere...
The only tech I want:
AC
Heated seats
Bluetooth/am/fm/aux sound system with good high and low ranges, but honestly as long as I have a diagram of what wires go where I can install my own like I did on my last two.
A backup camera for those times when I need to line up my trailer hitch but don't have a partner to guide me.
Beyond that?
Meh.
