It's because he's his manager, all the drivers managers go to the races, I think they show him alot cos it's unusual that a parent is a manager of one of the more succesful drivers who happens to be there when a camera is in his vicinity you may have even seen other drivers parents on the tv and not know that they were related, who knows?? If I were in an F1 drivers shoes I can say my dad would want to be there at every race like I would if my son was in that position too, ITV don't have control of the cameras at all the other countries apart from the british grand prix I believe, I have noticed that they show massa's father & brother alot too.
I think the money grabbing git is a bit harsh also, I'm sure that most of the drivers No1 objective in their career is to be succesful at racing and the money is part of the terrortry . I do believe all the drivers get paid a fair bit too you know not just hamilton, & all the drivers managers will have the same objective in mind, to make as much money as possible, that part is business, they wouldn't be doing their job very well if that wasn't the goal, & surely his rags to riches story makes him more acceptable to joe bloggs than some brat who's had daddy open doors and hands everything on a plate to him. Why can't we stick to discussing about the drivers skills, races , cars , tracks etc without all this I hate/don't like him or whatever, cos frankly it's getting boring now, none of us really know them so we can only go on the odd interview we see of them on race weekend , and to be honest hamilton comes across as one more talkative ones to me along with DC, Hekki, Vettel, Button, Barichello, truilli, massa, rosberg, where as some are like wooden robots, Raikkonan, alonso, piquet, kubica spring to mind but guess what, it doesn't bother me what their like or what they earn I just like watching the racing and the teams stratergies, not really a rant but that's all I have too say on it.
