My wife does not want, or need, anything other than what will aid her in figuring out the distance she can travel at a given configuration.

If we had a REAL "SOC" meter (it's coming !!!), then the chart can be modified to reflect good data. But, all we have to date is the 12 fuel bars.

She wants to drive 30 miles, and return. It's very easy to see that you need 9 bars at 60mph down the freeway, and 11 bars at 70mph. Obviously, a little cushion might be prudent, so 10 to 12 bars.

Now, she also knows that should the need arise, she can slow down to extend the

range, also based on the chart. No where did she need to know much math. Almost ZERO. No percentages of charge, no kilowatts / mile, etc.

She can also figure it out without ANY chart just knowing how to count the fuel bars, and remembering 7/50, 6/60, 5/70... and 10/38 for when things aren't going so well !!

I've given the chart to my 9 and 10 year old, and told them how far we need to go, and how many fuel bars, and have them tell me how fast I can drive down the freeway to do it. They haven't failed me yet !
