Setting aside the issue of whether inconsiderate use of vehicles is a newly millennial phenomenon for the moment and considering what this is in reply to: are you saying that the situation could have been avoided if your neighbour had been bullied enough as a child?
No, I am saying it seems like some millenials seem unaware of the possible consequences of their behaviour to others and to themselves. And if there is a confrontation, they'll report you to their teacher ( police ). While when I grew up, when I misbehaved in traffic, say concerning a taxi(cab), the driver would stop, make his opinion loudly heard, perhaps accompanied by a threat of violence ( this actually happened…
Of course that's not what you mean. I suppose you mean that instead of crying for help from the teacher she should have just swallowed it up and obeyed you.
But it goes both ways. Imagine you had a teenage daughter and she'd be accused of something, in her mind unrightfully, by some asshole neighbor. Would you like her to just swallow it up and do what he says? Or fight back, risking injury? Or call a mediator? That's the point of view of your neighbor.
If anything growing up with bullies teaches is that in the long run, only standing up to them works. But that's not what you'd actually how you'd have liked your millenial neighbor to react to you.
(I'm not saying you are the bully here. I'm totally with you on calling her out. But your "growing up with bullies" analogy is way off here and you need to consider all sides before drawing broad conclusions.)
