nearly fifty years ago, I can still recall an accident that I had. I was driving on my way to work, and pulled to a stop at a crossroads (with a "halt" sign). After checking left and right, the roads seemed clear. As I moved off, to go straight ahead, I ran straight into a motorcyclist. I genuinely hadn't seen him, even after I'd looked both ways. Unfortunately, in those days, nobody understood that I had genuinely not seen him, so I was prosecuted for driving without due care and attention, and was fined. It's only after reading this post that I realise what actually happened.
