Not all road incidents come from errors of judgements. There is metal fatigue, which if you read police statistics, is rare to the point of insignificance. Then there is the state of UK roads (even motorways) - see metal fatigue. Punctures. BUT.......... we are talking maintenance surely AND ..............

Acts of god like lightning (metal cars are a Faraday cage, you are safe, the car may stall). Floods, but there is judgement involved.

Then, as if white stuff and your breath in the air doesn't inform people of potential danger - we could blame the weather. But I won't.

Then there is the other guy, it always is.

And hands free phones are safe, no? NO! 70% of the danger (American survey in the New Scientist) comes from the way we visualise the person on the other end, detracting from essential attention to the road. The 30% is the way people fiddle with the phone - like texting.

No I would accept that the cavalier way councils and private individuals refuse to "maintain their borders" and allow vegetation to cover road signs; and it is getting worse. Drivers panic, make late decisions and sudden manoeuvres (or maneuvers in the US). So anything after that is the council's fault? But accident?

Did I miss any other excuse?
