Hi @cyberchucktx,
You can probably do all that with a modern car, but it will take more work than just using ODBII.
On modern cars, the ODBII messages are required by law (for emissions testing, etc.) and so the message format is public knowledge. Things like the vehicle speed sensor (VSS) are part of ODBII and you can calculate an average speed from that. The mass airflow sensor (MAF) is also part of ODBII and can help calculate your fuel efficiency.
However, the ODBII messages are sent over the main CANbus. Other messages are probably sent over it as well. A modern car might even have more than one CANbus or even other protocols. Things like braking, turning the steering wheel, using the turn signal are probably on some bus, but you have to find it for your car; it is often custom to the model or manufacturer. The current Carloop will access the main CANbus, but you will have to car-hack to discover all the other messages going on.
Maybe Carloop 3.0 can be designed to tap into those other CANbuses or other protocols. Once tapped in, some car-hacking might reverse-engineer the messages and discover how to get all that info. Personally, I am working on tapping into K-Line, which is older than CANbus.
The combination of Carloop and the expertise on a vehicle-specific forum might prove to be very powerful.
We all have to work on it to make it happen!
