I don't think it was "similar" at all. Remember Fernando had damage from Rubens crashing into him earlier. His car was pulling to one side. And he was also way down in the pack. I think he was fighting for one or two points. So, according to him, he was pushing like hell, to get more points. Webber was second, with a healthy car, and all he had to was hold station.
Sure, any driver can make mistakes, but I just don't see Alonso binning it if he was driving Mark's car in that situation. Remember Alonso's drive in Malaysia. He had no engine braking. His gearbox would go into neutral when he downshifting, and yet he drove a decent race until his engine blew.
Alonso, Hamilton, and maybe Kubica, are in a league of their own skill wise.
