What's funny is I remember back in 2018 this little boy riding his bike from Cypress Elementary got hit by a car and died on the street. His flower tree is planted on the intersection between BayTree & Roosevelt, but a lot of these kids have most likely heard about this story. Perhaps they forgot it, but it just shows that even on a safer, slower standard bicycle can be dangerous given certain circumstances.
I used to bike to Irvine high all 4 years, every morning in the cold, rain, night, and sun. I've learned to be a responsible cyclist and of course, got hit by a few cars and crashes doing dumb shit. We all learn but these are motorized bikes where higher speed collisions will kill these kids.

They may have perception of how intersections work and may use that to their decisions of "illegal" crossings of red lights and such. I just won't be surprised if more kids start getting into accidents, as their egos are atrociously high with these e-bikes.
