Percentage. Because a percentage is a percentage, unlike a "tesla mile" (insert your favorite definition here: rated, actual, estimated, guessed with a finger up in the air...).
Plus, I like math.

Percentage.
I use the following calcs in my head to get my range (I have a 75D):
% x 0.70 (to get approximate kWh remaining)
kWh remaining x 2 miles/kW (in winter, I know its really conservative)
kWh remaining x 3-3.5 miles/kW (in summer)
I've never owned an ICE with it's gas gauge calibrated in miles. It could be easily done by taking the car's combined EPA fuel efficiency number and size of gas tank into account. That's all Tesla is doing here.
I prefer my "fuel gauge" be calibrated in units of Empty (0) to Full (100).
It is not a very accurate predictor or range anyway... especially in winter... since it is just a linear representation from 0 to whatever your car/battery size EPA rating is anyway.
If I want to know how far I can really go, I pop open the Energy App, set it to last 30 miles and it will tell me how far I can go based on recent driving style, weather and so forth. On long road trips, I use my Nav system to tell me how far in actual miles and the Energy App to tell me how far I can go based on current, real driving conditions. As long as Projects > Actual miles, I'm good to go.
Actually that is quite the opposite. Range is directly proportional to the amount of energy in the battery. Percentage is proportional to what your full battery would hold today. How much is that today? How much was that on the day you bought your car? How much will it be in a year? Who knows?
Ideal range and rated range are just higher resolution battery state of charge readings (rather than 0-100% you get 0-310 or whatever your rated range is). Not sure whether degradation is included in percentage (it might re-scale itself for 100% to be whatever the max state of charge is possible after degradation), but it is in range (hence people often reporting degradation in miles, not percentages).range is an estimate, percentage is accurate. i use percentage
Yes, percentage is subject to fewer variables. But it doesn't account for the most fundamental piece of information that can be displayed to the driver, the amount of energy available for use in the battery. And that's what matters when deciding how far you can go.Percentage is affected by far fewer variables and those effects are realized over a much longer period of time.
No, it isn't.I prefer percentage as its a constant. The range is variable dependant on how fast your going, the temperature etc.
I dont need another thought process when I drive...
Range.
Nearly all BMWs dating back to 1997 and possibly earlier have had a range option. I'm certain all other luxury car brands have this feature as well

Let me emphasize again that is not correct. Range is simply kWh / (kWh/mile) where kWh/mils is a constant based on the model of your car. It is not impacted by temperature, speed, etc.That;s right. And the linear range shown on the battery meter when you switch to distance does not take that into account on Tesla cars.

And of course I realize range is just the number of kWh divided by a constant kWh/mi (for a given model). Yes it doesn't take into account speed, wind, elevation, etc. How could it? It doesn't know where you are going? That's what the trip planner is for.
But I stand by my assertion that range provides more useful information than does percentage. I am still trying to figure out what actionable information percentage is giving you.
