All I know is Honda stuff since I work as an engineer for them but
For throttle - you would need the proprietary CAN diag PIDs that control the FI ecu in order to control throttle. Maybe if you could find a toyota or subaru service tool and listen in on the bus as it talks to the FI it could make sense. The pedal itself is likely not a CAN based ECU, so you could not replicate it on CAN. The accelerator pedal position you see on the CAN bus is an output - broadcasted by the FI ecu.
We do not have an electronic brake booster so you could not control the brake pedal.
And, we do not have any ECUs that need to control the steering angle of the steering wheel, so you most likely won't be able to control it over CAN (for example if a car had an LKAS like system where ADAS-ECUs control the EPS you could hack steering wheel control).
