And a big one. Instead of displaying the EPA Estimated Range left or charge percentage, add an option to display the actual estimated range based on recent driving. The same one that shows estimated range remaining when you check your battery usage.
This one is so seemingly easy, and also so seemingly on point, I have always thought there is some regulatory reason why it isnt this way, because its obvious that it should be that way.
I dont know this, but (for example) I remember BMW removing the option for owners to easily defeat the "auto start / stop" engine system in their cars, that automatically stopped the engine every time you stopped the car, then started it back up automatically (while warning in their own manual that this feature could lead to additional starter wear).
When BMW first introduced this, it was an option in the idrive system to disable it. Later, that was removed and you had to code it off (BMW peeps know what I mean by that). When we dug into "why" that changed, we found it was basically because BMW was told that the gas mileage they quoted was based on the start / stop system being active, and if it was easily defeatable it didnt count.
That was sort of a huge deal for gas mileage not because of user facing marketing, but because of CAFE / CARB regulations........
Back to Tesla land........
The above suggestion is so obvious, and make so much sense, and would be so easy to implement (data already there) that it has to be a conscious decision to NOT be as mentioned by
@phxazcraig ... so there must be "some reason" as it cant be an oversite. It could just be Tesla hubris, but just as easily be some sort of obscure regulation.
