I'm interested in connected cars and this is a fascinating use case of CAN bus data as a conduit for gaining data insights from a vehicle without needing to rely on hardware sensors – these seem to be more vulnerable to the moving car environment than I thought, and prone to failure after a relatively short time.

So, if I'm reading this right, the hardware is still more accurate?

i'm not sure to be honest, how accurate are hardware sensors?

Right - that was kinda what I was trying to understand. I know they fail, but have to assume they're 100% accurate before they do. Sounds like a good idea for the environment, but what's the true impact of hardware sensors on the environment vs manufacture cost savings - would like to know the assumptions they used to get at that number.
Is it worth the risk to have (again) more data like that out in the wild (given their partner), and security issues around the ability to remotely alter the performance of your vehicle. I'm sure considerations like these were taken into account - Right?
But it does sound like a great opportunity provided there are measurable benefits to the environment, and would definitely provide huge benefits especially for the global fleet management market.

yeah, all good points. I know its possible to hack a CAN-bus (check out the Open Garages movement for example https://github.com/OpenGarages/ or Car hacking village https://www.carhackingvillage.com/) but from what I understand its pretty easy to hack a car just using an app, as there are so many third-parties with security vulnerabilities. https://www.extremetech.com/cars/179556-teslas-model-s-can-be-located-unlocked-and-burglarized-with-a-simple-hack

to be honest. i'm often surprised cars aren't hacked more often :)
