Listening to the radio while driving. They have filler jingles that make up 10 per cent, brutally loud advertising of the lunatic sort that account for another 10 per cent, announcements and boring talk by the host that fills another 10 per cent and when you expect some music they broadcast mad noise which accounts for another 30 per cent. And it is interrupted to boot by traffic warnings. And when there is a moment of silence they switch to the news that get repeated every half hour until your brain is coming out your nose as a white-ish liquid. What they do within the rest of the time I don't know as I miss it on the hunt for a better radio station only to get bored doing that too and switch it off.
