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.
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.
I think that pretty much sums up the entire ethos of Silicon Valley these days.
You've summed up every aspect of the Tesla. Especially now that real car companies are taking EVs seriously.
Reinventing the wheel.
But shittier!
Literally. And it sucks. There's reasons they don't do it like this anymore.
That makes your warranty expire faster. It's not in the users favor.
