For all the hand-wringing you'll see in news pieces about the scourge of youths on e-bikes taking over [insert formerly peaceful town name here], there are the personal anecdotes, and then there's the data.
While it's certainly true that there are jackasses on e-bikes, and that there are probably more of them now than there ever have been before, that only correlates with the quantifiable fact that e-bikes have become more popular. And as I'm sure you're aware, there's plenty of jackassery to go around on (and in) any and every type of vehicle, as well as on foot.
