Vehicle Engine Idles at 0 RPM?

Currently, the Wheeled Vehicle Movement Component has the engine idling at 0 RPM.

I could probably set a minimum RPM in C++. Obviously this, with the torque curve, will affect acceleration.

Is there reason for 0 RPM?

Is there an existing variable that I can set for idle RPM?

Are there plans to add engine idle RPM?

This solution just changes the RPM display. This might work in certain situations.

Will explore this idea. Thanks!
