It's also questionable whether Kirk really was just going for a joyride. There was a thread a couple of weeks ago debating whether he seemed suicidal.
I never got that impression. I always thought that he was deliberately intent on wrecking the car (and no more than that), and knew full well what to do and how to get out in time, so as not to endanger his own life.
And thus I still ask myself, why? Why would he wreck that car? Obviously he wouldn't do it to get back at his mom, so the logical alternative is, he wants to hurt the stepdad. And why would he do THAT....?

As for how I would handle this: I have no idea. Not a clue. I don't know what I would do or how I would react. Although I definitely would be asking myself what kind of person am I, that I would cause such a reaction in a kid. I may not be any kind of father, real or step, but I do have younger relatives, and if any one of them got so pissed off at me that they would destroy something I valued, I would want to know what I had done that made them do it.
