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.
