I wish the app let you put in the MPG car that its comparing to in the "gas savings" section. For a model y it is using a 28 mpg car. But, most friends I'm giving test drives to, are driving like suburbans and trucks at 13mpg. I mean, its easy enough to calculate the savings, it just would be nice to dynamically do it in the app. Right now in Idaho, home charging vs gas compared to a 13mpg truck, is 15 times cheaper.
