Everyone is wondering why capaldi’s doctor cant fly the Tardis, seriously did you even watch doctor who? Every doctor after regenerating becomes unstable often including memory loss, Paul McGann’s doctor literally forgot he was a time lord.

I completely agree that it should be no surprise that the Twelfth Doctor has trouble flying the TARDIS immediately after a regeneration.  Unquestionably the person who should know this the best is the Doctor himself.  So the question I have to ask myself is why does the Eleventh Doctor walk into a parked TARDIS and take off in it moments before he’s about to regenerate?  Surely the safe thing would be to just lock the doors and stay parked until the whole process is complete? 

And actually… the Tenth Doctor does exactly the same thing.  He walks into the safely parked TARDIS after stalking Rose and takes off knowing full well he’s just about to regenerate.  When, again, he could have just locked the doors and waited for his future self to take off once he was fully recovered.       

So basically I’m starting to think the New Who Doctors know exactly what they’re doing and are purposefully sabotaging things for their future selves.  Either as a kinda hazing process or just ‘cause the Doctor is always a little bit of a jerk to his other incarnations.
