When do you switch off your car stereo?

If you have traveled in private buses in India you might have noticed this - the driver switches off music or video several minutes before reaching the destination. With entertainment switched off, those last few minutes of a tiring journey become even more restless. I had always wondered why they switch off the music too soon.

Recently I have observed that the car radio becomes extremely distracting in the last few minutes of my drive. My concentration and alertness are considerably increased if the radio is switched off before I reach my destination. Even when I am driving a very familiar route, like commuting home from office, I find that it makes a big difference to my concentration if I switch off the radio a few minutes before reaching home. It seems as if I have to make greater mental effort when I am close to my destination, than in the middle of my journey. I don't know why it is so. I also don't understand why I had never realized this earlier.

Have you also observed this?
