*sigh* That's a good point. It'd be great while we were the only ones in our respective areas who had one. But if these things really caught on...well, things could get ugly quick. Especially if some of them get souped up. (I admit, the idea of a really modded fly-cycle is sorely tempting.)
Even pedestrians wouldn't be all that safe either. You could be walking down the street, minding your own business, when *BAMMM!* two numbskull flycycle jockeys smack into each other right overhead, and they and their parts start dropping out of the clear blue sky all around you, and maybe on you.
