It was you who chose it as a measure of success for the company! It'd be difficult to find any examples even if the scope was widened to include bike hire schemes, which have been around for almost a decade.

I agree that it'd be great if we could switch from using cars, however I'm not sure that scooter hire companies are the way to do this. Wouldn't it be better and less wasteful if people owned scooters? The answer isn't clear, but I'm worried because of the excessive waste generated by the cycle hire companies like Mobike and Ofo. I expect we'll see the same problems with the scooter hire companies too.
