Kids keep getting hurt and killed on e-bikes. Should parents be held responsible?

New York state requires riders of all forms of e-bikes to be at least 16, and New York City imposes additional restrictions, including a 15 mph (24 kph) speed limit. California, in contrast, has no statewide minimum age for lower-powered bikes, though riders must be at least 16 to use e-bikes that can go up to 28 mph (45 kph).
