Not to try and play on semantics but depends what you mean by "behave".
I certainly played safe for the first couple of weeks with only the occasional quick blast when overtaking. I am up in the early 3k miles now and am admittedly now happy to let loose when conditions allow.
Empty Scottish mountain roads with no "safety" cameras over the festive break was too much to bear without playing a little bit harder than normal, and a foot to the floor on the M1 at 3 am may have happened (or may not have if you are a rozzer reading this).
End of the day its a sports car and one of the reasons that I bought it. I am not into trying to kill cars but once you have clocked a good few hundred miles and given the modern technology you are driving I see no harm whatsoever of having a bit of fun.
I certainly condone taking it a bit easy until everything settles in and also driving as the conditions allow (advanced driver here) but from my experience your Roc will be like a tin of Ronseal - it does exactly what it says on the tin!!
Roc On!!
