If he does apologize in person, I'll eat my words, but I doubt he will. This is Schumacher we're talking about and since Barrichello is involved....
I'm pretty sure he hasn't, otherwise he wouldn't have come out saying "This is F1" or "Well, apparently I left him too much room, since he was able to get past me" later on the day. Barrichello would've come out saying he had instead of reacting like he has.
The website is just PR, obviously, that's why I said that.
