Folks,
As a relative newcomer to Tesla, but as an engineer who understands the power dynamics, I am very curious about something and wonder if I am alone.
My Model S Long Range gives me a "miles" number for the equivalent of my fuel tank - but it is never right, it always over-states. Equally the energy burndown display when on a trip is never right. And when the car tells me I should make it home with 3% to spare, I already know I won't make it home! All of which is fine, I can choose to drive like a monk (which you need to do to achieve the indicated range) but I don't choose to.
What I am curious about is this. With such a smart car, with so much compute power available to it, with so many options and adjustments... why does the car not give me the chance to see a REAL range based on it's learned understanding of my driving style? I understand we all drive differently and I also understand that averages aren't always helpful but this car is monitoring my every move: steering inputs, break pressure, acceleration behaviour in different weather and road conditions, etc. I am 100% certain that, if they wanted to, Tesla could allow my car to give me a highly accurate range: "Alastair if you drive like you normally drive you have a real range of 265 miles not 320" for example; in the same vein the energy burndown chart could set the baseline for a trip to be what the car expects ME to achieve, rather than Manny the Monk.
I do get that Tesla maybe don't want to advertise that the real range is lower than the published, marketed range but unless we're stupid we all knew that before we got the car in the first place. Now it's nothing but annoying that the range is just wrong all the time and you have to manually calculate the offset. Ironically the range indicator on my diesel BMW was much more reliable!
Any thoughts?
Thanks
Alastair
