NYC bike accident of "inevitable carnage" highlights the city's dangerous motorized bike and scooter situation

What I do not understand is why one of these below needs a licence and one does not. Both should.

Similar discussion, here.

California is considering a driver's license for e-bikes

In UK an e-bike must be pedalled to get battery assistance. No hand throttle allowed unless off-road/private land. Max battery power/speed limits. More power, more speed than that and ability to ride without pedalling and it becomes a licensable vehicle needing to be registered and insured and needing a driving licence. Makes a clear distinction as to what kids can and cannot ride.
