Well in that case make sure you have your car parked exactly where they want it parked to be refilled. Else you have to now experience additional stress of getting the car to that place and that falling levels of fuel in your tank at the same time. Its not like they track your car through GPS and show up at the exact place where you are empty.
Using GPS seems like a given for a service like this. At a minimum, I should be able to open my Yoshi app and say "My car will be [here] for the next 4 hours. Make sure it gets full".
"Rather than delivering “on-demand,” Yoshi users schedule refueling one time, typically at a place of work where they park for hours during the day without needing their vehicle."
and
"This “set it and forget it” approach allows Yoshi to optimize their delivery routes, explains CEO and co-founder Nick Alexander."
I don't think it works like Uber, where you can order for something and get it on demand. You need to tell them where you will be a few days in advance for them to chart our their route to finally reach you. You need to be aware/anticipate that you will run out of gas a few days before and then schedule the refill and keep your car unused for a good few hours.
