is a good starting point. But there are a bunch of buses on a modern car, some of them are critical, some less so. Some are firewalled off, others are open.

As you know you can get access to a lot of the car's inner workings by plugging into the ODB2 port. Its perfectly possible to brick some cars by fuzzing the ODB2 port.

In principle, most things in cars _should_ fail safe. even if they are electric or talking over a bus of somesort.

OBD is a diagnostic bus. On modern car the access is authenticated on several layers (eg. guest, carmaker, ECU supplier). I would not call that interesting. Accessing a CAN/FlexRay/LIN/Eth bus is better.
