The Tesla meter is not a learning algorithm. It simply takes battery voltage and creates a number from it regardless of how or where you drive. It is about where cars were in 2000.
Newer cars, like the i-Pace, use a learning range meter. It will look at how you have been driving, the temperature, the HVAC setting, and IIRC even the topography (hills) to estimate range.
The i-Pace is 'predictive'. It tries to estimate how far you can go this trip. The Tesla is not, it's a gas gauge needle. A full tank will show the same range no matter what. It's a marketing issue. Do you want to show people a nice number, or do you want to give them an accurate range? But it can work against you. My i-Pace is still showing over 250 miles on the range. My blue Volt is reading 59 miles, not 53. If an i-Pace were a Tesla it would be showing 234 miles every time you charge it 100%.
This will be the second great application for predictive range estimation. The first one was for towing. Your truck would quickly guess based on the load what your REAL range would be, which can be 50% of normal. It's very easy to run out fuel towing.
Ditto for EVs. I want to know when my range is going to be bad ASAP. I do not want an optimistic or pessimistic number. I want a realistic one. If my Volts will go 59 miles the way I drive, then that's what number I want on the dash. If my i-Pace will probably only go 160 miles today, I want to know ASAP. Don't tell me 234 miles to make the Sales Dept happy.
