Perhaps I'm missing something here but since when have mud and diesel even been remotely similar? If someone can't see mud on the road - in particular enough to cause a car to career off the road then they need their eyes testing.

Your statement is the equivalent of someone stabbing themself with a knife and then you saying something as stupid as "oh you couldn't have done as i've never managed to stab myself with a spoon".

Perhaps a bad example on my part as judging by your apparent level of reasoning, I wouldn't be at all surprised if you were dim enough to have stabbed yourself with a spoon at some point.

It would appear your argument is somewhat irrelevant and ill thought out, especially as you even state "spilt diesel that I couldn't see".
