A Tesla influencer randomly caught his odometer double-counting mileage on video. Wild.

    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.

          You’ve summed up every aspect of the Tesla. Especially now that real car companies are taking EVs seriously.

          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 have test all three methods. GPS is the best, but it has drop outs. You can add an inertial gyro system to compensate, but that becomes sloppy the longer it goes without GPS.

            The tire method has a lot of variances, but the measure at the transmission is often worse.

              So if I replace the wheels on my car with monster truck wheels, I’ll be able to cheat the odometer?

                Well yeah. My bicycle odemeter has settings for different size wheels.

                We used to take vehicles in for calibration and then all runs had to use the same psi in the tires.

              It absolutely does. Typically, all 4 wheel speed sensors are polled and averaged, so unless you’re doing lots of extended 4 wheel burnouts, you’re talking an incredibly small margin of additional error.

            …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.

        You’d think they would make it increment every half mile instead of doing something stupid like this.

          Yeah if you’re gonna do a fraud at least put the minimum thought into it. It’s disrespectful is what it is. Gives honest grifters a bad name

            Except in this case they’re defrauding customers instead of corporate like in Office Space… not quite as fun.

      You can remove YouTube videos from your watch history, so they don’t influence your algorithm.
