Probably to let the other drivers at dusk to see YOUR TAILLIGHTS as the light of day starts to dim.......
We have tail-lights, they come on with sidelight and headlight. Foglights are supposed to be only used (in the UK) when visibility drops below 100 yards; not when the sun is shining, mid day in summer
As I said above, I drive all day and I've seen it all. I don't mind so much people on their phones talking but it's obvious when their phone conversation is hindering their ability to operate a vehicle. And signaling also irritates me but I've learned to watch people's movements and hands in their mirror or through their windows to make an educated guess as to what bonehead move they're about to pull...
People using mobiles - with you there. Last year, saw one up on that - a guy obviously heading into work, shaving while driving!
Signaling, again, we're of the same mind. You know you're the tourist in town when you're the only one using your indicators.
When life gives you lemons; don't make lemonade.
Give back the lemons. Why were the lemons free? What's wrong with the lemons?
Do Not trust the lemons...
