I don't believe taxiing too fast is normally a problem at Easy but the question of fatigue most certainly is!
Fatigue, morale and pressures real or perceived all take their toll on the safe operation of aircraft.
I have no idea what caused this particular incident but I'm really sick of your continued denial of certain very real safety issues which exist and continue to exist while managers are in denial.
Don't get smug or complacent, you said it yourself :-
' No doubt the official investigation will get to the truth! '
