I've got "disruptive," "obvious," the free space in the middle, "synergy" (which I'm counting combination of technologies for), and "ride-share".
Mostly because people behaving like idiots riding scooters on the sidewalks leading to at least two serious accidents per day. Bicycles are still allowed.
Lessons learned : The urban infrastructure needs to have space for the eScooters to co-exist with other participants (cars and pedestrians alike)
I see a ton more scooters on the sidewalk than I see people riding them. From my perspective these scooter companies have greatly overestimated the demand.
That said, I'm not sure how sustainable their business model will be because riding Lime and Neuron (a Singaporean competitor that we have operating in some Australian cities) is probably leaning me more towards wanting to get my own e-scooter than regularly hiring theirs...
I get that it feels like a 2-dollar-Harley, and once parents realize that their kids are both at risk AND it costs as much as an Uber, I expect loses to grow.
Unless something drastic happens and the cost drops dramatically.
I could see scooters completely wiping out local ride-share, taxi, and bicycle shares in many places.
But again, people have been injured and because of that, along with the excessive inventory that has littered some areas, cities are cracking down and writing new regulation to curb their use. In the short term they will win and we might not enjoy their full potential for awhile.
