My dad gave me a lift to the railway station the night I bought my defective railway ticket. As he was reversing out the drive in the dark, Dad made the following observation:
I remember when reversing lights were bright enough for you to actually see where you were going. You used to get two. Then some bright spark in London somewhere decided that two white lights on the back of a car looked like a car coming the other way…
Well they bloody well were a car coming the other way!
So now you know where I get it from.
