I wonder how many drivers of vehicles that are equipped with Daytime Running Lights (the headlights that turn on when the car turns on, so they are always 'on') are aware that they need to turn on their REAL lights when it gets dark outside. Apparently quite a few of them are NOT aware ... I drove home with three of them this evening. They had NO rear lights, and when approaching them from behind, the only reason I saw them was the reflection of my own headlights on the backs of their vehicles. So dangerous.
I think these vehicles either need to have a "it's dark, stupid, turn on your lights" indicator, or when people flash their lights at them, these unaware drivers should get a clue instead of flipping us the bird.
I am done, now.
