Both percentage display and current miles (given in EPA) are not optimal.To me, that's why using percentage is much less confusing/irritating than using the miles number.
With the percentage, you’re constantly translating (guessing) on what you think you have left based on experience with the car you’re driving. If the car says 37% left for example, how many miles is that? I don’t know exactly. I could say its *around* this much give or take, or I could be conservative and say I have at least this much. But there’s no computer behind the scenes analyzing my current and past driving habits and showing me an estimated miles left to empty number. And of course, everyone who says it doesn’t really matter is correct, it doesn’t….except Sometimes I don’t feel like charging it. Maybe 20% will get me to work where its cheaper to charge etc….
With the EPA miles number, well, that’s not good either->we all know that one is overly aggressive and if say it shows 50 miles we’re not going to get 50 miles UNLESS we slow down to about 50-55mph and go super easy on the accelerator.
So no, we could argue about which one of those silly numbers is better but the truth is, Tesla can show us a GOM. I know this because one is present if I choose to display a graph. Hell, what I really want is a percentage (which can be inside the battery) and a GOM next to it. It’s not like I’m asking for a Heads-up display or a gauge console behind the steering wheel.
