Tesla YouTuber Bjørn Nyland spends a lot of time driving around with the Scan My Tesla app overlaid on his stream.

Lots of interesting real-time data in there from the motors, battery, and cooling/heating systems.

On the Model 3, it’s particularly interesting how it will start to generate extra heat from the motors as you approach a supercharger. Routing that heat to the battery brings the cells up to optimal temperature to allow faster charging.

To anyone who wants an introduction to car hacking, I recommend the Car Hacker's Handbook, which is available for free online [0]. The book has a security focus but is also interesting to skim if you just want to learn a bit about what goes on in the networks in your car.

Not much to see here...

... could have been any generic "Get data from my OBD or CAN bus for [car model]" article.

This is kind of “system programming” that is interesting.
