The problem with on-demand is that it takes time and energy to go actually demand it. With radio, if you are working in the garage or garden or on a jobsite, you just tune into some station, and you get guys talking about fixing cars or something and that's it. With youtube or spotify or whatever, you have to go search for something interesting, it lasts for 15 minutes, and then you have to search again. Or maybe you get a podcast that last an hour. But it's never set and forget like radio. It's all just a waste if time unless you have something very specific you want to hear, rather than just background chit chat.

Not a trucker. there are some areas where data is not available. In some countries I use pre-paid mobile phones. I turn off data in those places.

I (try to) walk at least an hour a day. I also hike trails. Ever seen a bear wait for Click and Clack[0] demonstrating the noise a worn CV join makes? Nor have I. ;-)

I have several hobbies which involve manual labour, but no major attention required (weeding, kneading, etc.). I can listen to the radio and still enjoy my hobby.

Ah! Just posted about Click & Clack.

I have heard some here and there, but nothing close to them. :'(

I have heard a station in California (do not know call sign), the motor man, or the motoring man. There was also in Detroit a station where two guys tried to pick up similar like C&C, car show or something.

Ask the A&Ps is a podcast that’s a pretty similar concept but for general aviation.
