For me it would be not needing to experience the little bit of stress I see when the fuel indicator is edging down to 1/4 tank and wondering when I'm going to squeeze in a trip to the gas station when I'd really rather be somewhere else.
I also don't get these 40 minute estimates. On one of my little motorbikes I used to fuel up and back on the road in no more than 3 minutes, and my truck doesn't take more than 5-8.
First world problems for sure, but I'd happily pay to be rid of that inconvenience. And while they're at it, I'd pay an extra $10 for them to do a quick wash of my car once a month.
Its not like they track your car through GPS and show up at the exact place where you are empty.
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.
That makes much sense for the 1.0 version, but I have to think my GPS vision is on the 2.0 roadmap.
