Agree, it seems to assume that the unit of mobility is something larger, like a car. When the fundamental unit of human mobility is just that, a human, since they are inherently mobile. We would do better to describe cars as macro mobility than scooters and bikes as micro. Pipe dream, I know.
Speaking only for "micro mobility", it seems useful to distinguish allowing someone to travel within a city from between cities from between continents. Sure, it's mobility, but there are different kinds or degrees of mobility.
