One of our readers, Miguel, sent us a link to this incredibly useful iPhone app. It's called The Slow Down App.
Listen to music on the phone whilst driving. Great. If you are driving faster than the speed limit, the music starts to slow down. If you exceed the speed limit by more than 10 km/h, the music stops altogether.
I was driving on the motorway north of Copenhagen a couple of weeks ago and I stuck right to the speed limit the whole time. I was the slowest fukker on the motorway. That's a lot of music-less cars.
