Update to Scooter Stats

A few weeks ago, I posted some preliminary statistics on Bird and Lime electric scooters (aka dockless mobility devices) in Indianapolis, comparing the scooters here to those in Louisville. I then spoke with Alison Griswold at Quartz to refine the population of scooters we were analyzing, and have since updated the numbers. The main takeaway is that when we limit the scooters to only those devices whose last ride was prior to December, the lifespan I previously found (~42 days) declines to 28 days. This has implications for the other stats we reported as well, and those new calculations are summarized in the table below. Thanks again to Nathan Stevens for his analysis of the Louisville data.

This also changes the comparison of the two companies, Bird and Lime, who are active in Indianapolis.
