I'm surprised there isn't more info available to compare vehicles/tyre wear. There's plenty of real-world driving going on, so you'd think someone would have measured tyre replacement frequencies.
Tires and driving styles vary a lot, so it would be really hard to come up with some aggregate numbers. Maybe you could compare the same very popular tire on different cars that still have enough data points to average out differing factors?
I reckon that the different driving styles could be partially dealt with by considering different classes of car. E
G. Fast "prestige" cars will tend to share certain driving styles and be quite different to cheaper run-arounds.
Ideally, it'd be great if insurance companies made a big push to get some kind of standardised "black box" that drivers could fit. As well as providing extra stats, I think they'd be great for detecting illnesses. A simple driving ability stat could be produced from the typical acceleration/braking timings - smoother is better as it shows good anticipation by the driver. If their stat starts decreasing more than expected due to aging etc. then the driver could be alerted that they should consult a doctor as it could cognitive decline, eye problems etc.
