They were mocking someone for choosing to do without technology, it was just a snippy retort. Why aren't you jumping down their throat?

edit: Turns out I was wrong about the parent's intent. For what it's worth, I do actually drive in silence a lot. There is something about a vehicle in transit that temporarily relieves you of responsibilities outside of the drive, and it's a great time to reflect. I could reflect on this comment thread, for example. Two times in the past few months I've been wrong about someone's intent on HN and met them with a little too much spice than was fair, that's worth reflecting on.

I sometimes drive in complete silence. The friction between the tires and the asphalt is close to white noise. It contains a range of high and low frequencies that you can't easily filter out, something that I tried to deal with at a computer vision class project involving self-driving tech. Also it can be amazingly therapeutic.

I drive in silence. I don't understand why some people feel the need to _always_ be listening to something.

I do. Is this unusual?
