I can't help thinking that the Police's mantra that accidents in fog are caused by people driving too fast is a bit simplistic. I don't suppose that the syrup lorry was going to fast but he was still involved in the accident. If you are driving a smaller vehicle it's difficult to get it right, too fast you risk hitting someone but too slow and you risk being run into. If you slow down on a motor bike and someone runs into the back of you it's not much consolation blaming the other driver.
