I would like to utilize a curve tangent or a curve normal in my driver (i.e. in its Scripted expression)
When working with geometry there's the "Sample Curve" node for that. Is it possible to obtain those values in a property driver?

I would like to utilize a curve tangent or a curve normal in my driver (i.e. in its Scripted expression)

What I am trying to do:

1. have my vehicle model follow a path object
   Done - I used the "Follow path" constraint on the vehicle parent object.

2. have the wheels rotate according to the distance travelled along this path object
   Done - a driver on the "Rotation X" in Delta Transform does that for me. (The driver references the offset of the aforementioned "Follow Path" constraint.)

3. have the wheels steer/aim according to the tangent (or the normal?) of the curve
