I'm in the industry and most cars 2008-2017 or thereabouts have multiple CAN buses exposed on the OBD2 port. One (powertrain CAN) on the regulated 6/14 pins which is guaranteed to answer the emissions messages but probably exposes other stuff too, and then others (body CAN, infotainment CAN, etc) on other pairs of pins.
Post-2018-ish, they tend to have a gateway module, and accessing anything interesting requires you to get into the wiring "behind" the gateway where all the internal buses are. But that's also trivial, in most cars it takes about 20 seconds once your wrist knows the way.

Or knowing the messages it sends. It's only $20k because it can be.
> or some serious reverse engineering chops and weeks of time to figure it out.
Which someone then packages into a $500 car-stealer they sell on aliexpress and then all the criminals have to do is buy that thing and push a button.
