It's long been a big complaint - the guess-o-meter - across many forums. Nissan made some improvements, supposedly, but I completely agree with your preference.
I do my own range calculations. They aren't very accurate either but at least I know my basis. I have a general idea on the miles/kwh (that's the way Nissan chose to display energy consumption) for different conditions. So, if I know the distance I will travel and the rough distribution of conditions, I can quickly calculate kwh. Then, I convert that into bars: total capacity is 24kwh and there are 12 bars so each bar is 2kwh (this isn't exactly true, but close enough). For me, the crude numbers I use are: summer city driving: 2.5 miles/kwh summer 40mph roads: 4 miles/kwh summer freeway (65mph): 3 miles/kwh winter city driving: 2 miles/kwh winter 40mph roads: 3.5miles/kwh winter freeway (65mph): 2.5miles/kwh I will say that my numbers, above, are pretty loose. I always end up consuming more bars than I estimate. I don't know if that's because the gage isn't linear or because I'm not including enough for overhead, such as heat, A/C, etc. I haven't tried to be more accurate because, So far, it has worked well enough.

It varies too much. If you're going uphill, it gives a smaller number of miles remaining. Then when you get back on level ground, miles go back up. Going downhill it changes again. Talk about range anxiety. I'd much rather have just as Empty-Full gauge as a regular car does. Then I can see just how fast the gauge is going down and estimate for myself. I think most people who have driving ICE cars all their lives have the same instinct. The "miles remaining" is only a rough estimate anyway, just like the rough estimate I'd make by looking at the Empty-Full gauge. I'd be interested to hear other people's take on it.
