Having started driving in the age of 99¢/gal gas, I am highly sensitive to price differences between stations, and I choose between 3 stations that are always within 5¢ of each other. I am typically not so price sensitive (with other purchases), but with gas I make minor schedule/route deviations to save <75¢ on a fill up. Curiously, because this startup charges a monthly convenience/subscription charge—instead of an incremental fuel charge—I was actually willing to consider it. But when I did the math, it didn't come close to making sense.<p>Having a service like this would save me some amount of time, I suspect that if I significantly relaxed my fueling station choices, it would cost me much less than $15/mo, and the inconvenience of filling up would be diminished nearly to zero. There are stations very near where I live, so route deviations would disappear, and the lines are never very long.<p>Basically, I think part of the allure of a service like Yoshi is it removes the decision paralysis that results from having many different gas stations available, and having to choose when/where to fill up. Ultimately not a game-changer for me, but I appreciate that it makes me consider alternatives!
