I suspect the cost of driving easily overshadows the cost of electricity, considering that even inflated California electricity rates price a kWh (of which these scooter batteries hold about one quarter) about the same as the incremental cost of driving one mile.

Whether it's trifling depends on how far they have to drive for each scooter. That cost is sunk if they "recover" it or not, unlike with the electricity. According to the article, the company has made it a bounty-hunting model, so even if the total area is only a few miles across, just getting there is no guarantee.
