I was #driving on a #motorway though #stormy #weather today and, at midday, it was so dark that it felt like the Sun had already set. Most drivers were using their lights, and rightly so. However, there is always a significant minority of drivers who refuse to turn on their #RearLights in such conditions. They become virtually invisible in heavy rain from behind. Most #cars these days have #RunningLights in the front these days but I don't think there's a requirement for having red rear running lights and some seem to think that that somehow magically makes them visible from behind.
