Unaccomplished yes, inexperienced no. Apart from her lower formulae experience she tested a Renault for 300km last year.
None of which will help her understand the controls of the MR-01
I'm not denying she's a talented driver, she's probably a faster race car driver than any of us here, but the fact she crashes in her first outing in the car has to raise suspicions as to whether the accident was avoidable or not.
It could be a fault with the car, but given this was her first time in the car, it would seem more likely to be down to human error on her part. Well wait and see as no doubt marussia have engineers pouring over the logs tying to find out what happened. If this was an error with the car, what happened if it did this down the pit straight on race day and ploughed straight into one of the pit crews ?
That prospect is even more scary IMO.
