See the Ford bounty for context.

Requirements

  • unit tests
  • works for all supported cars

We also need to answer these questions:

  • has Tesla ever changed the APIs we use?
  • are there any variants of our supported cars that won't work?

The steering api on Model 3/Y is consistent across HW2.5, HW3, and HW4.

HW2.5 sends the same signal for longitudinal control but at a different frequency (40Hz instead of 25Hz).
Additionally, some HW2.5 vehicles without ACC capability can't utilize longitudinal control, likely due to a different Drive Interface firmware version. (HW2.5 without ACC 37048455b52d3740/000002ab--e5681a32b4)

The current issue is that these cars still match the fingerprint because they share the same EPS firmware.
As a first step, we should probably add the Drive Interface firmware version to the fingerprint.
