It is of course all an opinion. You may not agree.
Clarkson is all those things but he actually is very intelligent. When he puts forward some extreme view, he argues it well and most of us know he is playing to the crowd (he is a cyclist). He can make a report on a Vauxhall Vectra entertaining. It is rather beyond me that you associate him with danger.
Evans is none of these. He is just annoying. Rather like the dimmer half of Jedward. He does not put forward a case for anything, he does not ever step beyond his own world. Rather as toddlers are by nature self centred, he has not grown beyond that stage. But is that perhaps why you like him?
