PERF_STEERING_ANGLE

What it is

Front bicycle model steering angle for vehicle

Angle is in degrees. Left is negative.

This property is independent of the angle of the steering wheel. This property must communicate the angle of the front wheels with respect to the vehicle, not the angle of the steering wheel.
