Well, Senoufou, we are all human beings. No-one decides to fall off a ladder or trip up on the pavement, or eat dodgy salad in order to get food poisoning. It's so easy to get all sententious and declare that "every so-called accident is someone's fault." I dropped a cup of tea on the floor this afternoon. I suppose it was my fault. I tripped on my stair carpet last week and still have the scabbed-over graze on my knee to prove it. My fault. Do you think that either outcome is what I wanted? Just because someone gets behind a wheel it doesn't make them a demon if they have an accident. Circumstances alter cases. Most accidents are caused by driver error, which can mean a momentary lapse of concentration or a poor snap decision. Just a few are caused by lunatics, ignoring the law about using mobile phones, drinking or by inexperience. As a society we could do a lot to fix those things, but we tend to put our priorities elsewhere.
