I'd be really interested in the real-life lifespan of scooters, including theft, ditching (cue pictures of piles of ditched e-bikes sitting in a stream), customers doing stupid things and breaking them etc. Also on real-life utilisation percentage (ride length, rides/day). Together these could make an order of magnitude change in the profit expected.<p>The article is making the point that changing the key parameters dramatically varies your expected profit, but the message I'm taking away is you can make any business model look arbitrarily good or bad by slightly tweaking your estimates, and the more multipliers in your model, the more 'flexible' it is in this way.
