Exactly, being put under pressure by schuey was easy to brush off if you made a mistake, but being put under pressure by your new rookie team mate is another, that why I say he's possibly under more pressure now. plus he's in a new team and doesn't exactly know where their priorities are ( bearing in mind that they've brought hamilton up from 9yrs old.), he must be beginning to wonder now.
I've been watching F1 RELIGIOUSLY (some times obsessively) for many years, and know that mclaren have some strange team orders, 'pre-race', out of the earshot of the stewards, and one of their most popular rules (orders) is "who ever get to the first corner first wins the race" (removing any unforseen incidents). And I think that this is what order was given on sunday, and alonso tried to get there first and make the race his.
Remember Senna and Prost at Sanmarino in '88? the same happened there, BUT it was Prost who got through the tamburello first but Senna wasn't having any of it and forced his way past his more experienced, world champion team mate, which didn't make Mr Dennis very happy.
Prost was feeling the same presure from his younger less experienced team mate as alonso is feeling......and senna went on to win the world championship that year!!
Is that obsessive enough for you?
