Using your numbers, that's $6-9 of total gross revenue per day, with up to 3 pickup/charge/redeploy charges per day. That would mean a lot of days with a net operating loss even before fixed costs and debt service are considered.
Pickups to recharge only happen once a day with birds AFAIK, and I don't know if half charged scooters are recharged. Most people do not use the full battery capacity of these things, which are 20+ miles. More charge used usually means more time used, which means more money.
Lime's scooters have a 20 mile range and charge $.15/min + $1 per use[1]. So assuming an average speed of 10mph, using the full battery would be 120 minutes of use, which is $18. Then you add the $1 unlock fees which would of happened multiple times, and you have something of at least $20 average gross revenue per day of a 'fully used scooter'.
These scooter companies probably have better data on average usage, which is probably why they are getting such huge funding amounts due to the $$$ potential.
