Assumptions for the 3 scenarios (same as detailed in Jan Kamps/ TechCrunch analysis):
Base Case - 300 rides scooter life;
5 rides of 20 minutes each, per scooter, daily;
customers charge 50% of the times
SturdierScooters - 500 rides scooter life;
7 rides of 25 minutes each, per scooter, daily;
customers charge 75% of the times
SuperScooters - 1000 rides scooter life;
5 rides of 20 minutes each, per scooter, daily;
charging costs are much lower but acquisition cost per scooter is much higher
