I seriously doubt that tiny burg of a town has a fleet of electric taxis and or owners that will keep it fully loaded 24 hours a day. Even if they do the numbers are tiny. At $1344 a day gross at full usage minus the costs, I don't see how it will ever be "very profitable". Even the owner stated “You notice there are not too many electric vehicles on the road,” he said. “So it’s not something that I expect to become rich overnight or something like that, but it’s a good cause [and] good for the environment.”
It only took a $800,000 grant from our/their tax dollars so he could make a few hundred dollars a day, maybe.
