Daytime driving lights

[justracing]

I readily admit that it's hardly historic related but it'a subject worth raising amongst members of the older generation, specifically what idiot came up with the idea of daytime driving lights which only operate the front side lights? It's beginning to drive me insane when approaching vehicles with absolutely no rear lights driving in gloomy/darkening conditions and then glancing behind having overtaken to observe two meagre illuminated front side lights. It would appear from observation that the drivers of said vehicles seem totally oblivious to the fact that they cannot be seen from behind and present a real danger on the road. The old adage that I was taught was to see and more importantly be seen. Maybe it's just me being a grumpy old fart.
