I want to use getCarControls api to collect steering information when driving a car in Unity by keyboards. But the steering angle always returns 0.
Is there any way to get steering angle by api in Unity

environment：
Windows 10
Unity 2019.3.12
Airsim [1.3.1]

This is a preexisting bug in the Unity I think, and seems to be related to #2937, at least based on my older description
