Yes I saw you say in F1 terms the first time. Considering the medical alarms in cars are set off at 15g as you mention, it was far from mild. Take Perez's and Massa's crash in Canada, that was 27g and definitely not mild. But that just shows that no incidents are the same (obviously). There have been far worse apparent incidents in the past e.g. Webber, Valencia 2010, that turn out to be insignificant whilst there have been incidents that don't look life threatening yet were e.g. Senna. So perhaps there is more that meets the eye in how hurt. Alternatively, McLaren could just be playing it safe especially since
its their star driver that they shelled out a lot of money for and the
championship hasn't started it yet. Anyway, why should it be any of our business as to how 'hurt' he is? Mclaren repeatedly mentioned he was in an ok state and that should be enough. Besides, he's left the hospital so it doesn't matter and Mclaren are still taking part in the next test which wouldn't happen if any of the tin foil hat stories were correct.
