I don't want to get into a pointless debate which just ends up with two different opinions, so all i will say is this.
I find it strange that people ( particularly F1 twitter ) make such sweeping statements ( one error while in dirty air means a "true weakness of character"?
) I think its difficult to say that about anyone who reaches a level like that in F1, never mind someone with 4 championships at that level. Everyone will have their favourite drivers and some they like/rate less, but the comments people make in my opinion often show a lack of understanding of the pressure and sheer competition at top level sport and/or a selective memory when talking about whichever driver they dislike.
That applies to all drivers, but for whatever reason some people feel a strange need to dislike Seb. The Race did an article on it this morning actually.

Not hoping to start an argument here, it just confuses me when people comment like that, so that's all I will say about it
