Lime scooters need an age limit

Do Seattle’s rentable scooters, bikes, and gliders have any kind of age limit? In my neighborhood, I see totally unsupervised kids no older than 7 or 8 whipping around narrow, hilly streets, riding at top speed down sidewalks, and generally displaying all the lack of impulse control and good decision making you would expect. It’s hugely dangerous for everybody, and I don’t understand how it’s legal.
