There was a piece on a fairly recent Smashing Security podcast that said that some car manufacturers are sending data to the insurance companies anyway.
Yup, this is why in my own vehicles I physically disconnect the system that sends these messages.

What's a good resource for someone who wants to do this but doesn't know much about car computer systems?
Automotive groups, forums, clubs that focus on your individual brand of vehicle, or better your specific vehicle.
Brands generally keep the same style or type of system across their range, so if it works for one car in the brand it is much more likely to work on another.
My Chevy volt, for example, has a separate controller from the engine controller, and I could just airgap(unplug) it.
Others you may have to remove the antenna, replacing with a dummy load to not permanently damage the circuits.
