I tend to daydream a lot at the traffic lights, which inevitably results in the people behind tooting their horns when you've just missed the light change.

I noticed in Bulgaria that they have a countdown on top of each set of lights, including the pedestrian crossings, which counts down to the next red or green light, so there's no chance of you missing it.

I did try to take a photo of it one day, but nearly got run over, so I decided just to leave it.
