I admit I didn’t watch the video — I’ve trained YouTube’s algorithm well at this point and don’t want Tesla content — but what the fuck is a predictive odometer? The tires roll a certain distance. We’ve had odometers for like 75 years.
The article mentions that Tesla is kind of justifying the behavior by saying it is based on energy consumption and some other bullshit. The expectation according to SAE, which I find very interesting, is to be in a range of +/- 4% and for GPS enabled odometers+/- 2.5%, Tesla is missing the mark for at least 36%.
So we traded a proven, reliable, physical laws based method (wheel roll) in favor of unreliable electronics. Nice.
Electronics can be extremely reliable, but Tesla chose to be sleezebags.
It's not really that reliable as it it will depend on the diameter of the wheels that can vary with pressure, wear, and and actual tyre size.
A better method may be a sensor like the one used in optical mice.
...but what are we actually trying to measure here? The miles travelled, or the wear and tear that's caused by the wheels spinning?
Mileage by counting the number of rotation of the wheel.
The mileage is a measurement to give an idea of the wear, combined with other information to give a holistic view of the state of the car.
Fair, and thinking about it it doesn't account for unnecessary wheelspin
You've summed up every aspect of the Tesla. Especially now that real car companies are taking EVs seriously.
Reinventing the wheel.
Literally. And it sucks. There's reasons they don't do it like this anymore.
Man, something I love is un-steering by simply reducing my grip against the wheel so it slowly resets to neutral, my hand's friction making sure it doesn't do so suddenly. This shit ass shape would make that impossible. It's like they hate driving.
Now you can un-steer way faster! /S
imagine the hand smack once the other side turns in... ow
But shittier!
That makes your warranty expire faster. It's not in the users favor.
I think that pretty much sums up the entire ethos of Silicon Valley these days.
