Vehicle Movement at beginning of path

Beginner Questions
1

I have an infinite world that allows players to switch from 3rd person control to an overhead RTS style mode for certain interactions (Terrain modifications in vehicles mostly - excavators, dump trucks, bulldozers, etc).

I’m trying to find a way to give the initial path when you make a vehicle move look a bit more realistic (reverse and turn if needed, or generate the path based on a max steer angle from the units initial rotation). Is something like this already implemented (I might be slightly blind, but couldn’t find too much), or will I need to write my own?

I have a general solution, lacking polish. But I like how it looks so far (in case others have a similar problem) - This is using Edy’s Vehicle Physics (I modified his code a bit and changed his function calls to my own, since I like capitols and underscores more - SendInput == SEND_INPUT more or less):

`
void FOLLOW_PATH ()
{
if( CURRENT_WAYPOINT >= PATH.vectorPath.Count )
{
CAR_CTRL.SEND_INPUT( 0.0f, 0.0f, 0.0f, 0.0f, false );
PATH = null;
return;
}

POINT = TRANSFORM.InverseTransformPoint( PATH.vectorPath[ CURRENT_WAYPOINT ] );
ANGLE = Vector3.Angle( ( PATH.vectorPath[ CURRENT_WAYPOINT ] - TRANSFORM.position ).normalized, TRANSFORM.forward );

if( POINT.z > 0.0f )
{ 
	if( MOTOR == -1.0f && ANGLE > 45.0f )
	{ 
		MOTOR = -1.0f; 
	} 
	else 
	{ 
		MOTOR =  1.0f;
	}
}
else if( POINT.z < 0.0f )
{ 
	MOTOR = -1.0f; 
}
else                     
{ 
	MOTOR =  0.0f; 
}
	
if( POINT.x > 0.0f )
{ 
	if( MOTOR > 0.0f )
	{ 
		TURN = Mathf.MoveTowards(TURN,  1.0f, Time.fixedDeltaTime * 5.0f); 
	} 
	else if( MOTOR < 0.0f )
	{ 
		TURN = Mathf.MoveTowards(TURN, -1.0f, Time.fixedDeltaTime * 5.0f); 
	} 
	else                   
	{
		TURN = Mathf.MoveTowards(TURN,  0.0f, Time.fixedDeltaTime * 5.0f); 
	} 
} 
else if( POINT.x < 0.0f )
{
	if( MOTOR > 0.0f )
	{ 
		TURN = Mathf.MoveTowards( TURN, -1.0f, Time.fixedDeltaTime * 5.0f ); 
	}
	else if( MOTOR < 0.0f )
	{ 
		TURN = Mathf.MoveTowards( TURN,  1.0f, Time.fixedDeltaTime * 5.0f ); 
	}
	else
	{ 
		TURN = Mathf.MoveTowards( TURN,  0.0f, Time.fixedDeltaTime * 5.0f ); 
	} 
} 
else
{ 
	TURN = Mathf.Lerp( TURN, 0.0f, Time.fixedDeltaTime * 5.0f ); 
} 

CAR_CTRL.SEND_INPUT( TURN, Mathf.Clamp( MOTOR,  0.0f, 1.0f ), ( -1.0f * Mathf.Clamp( MOTOR, -1.0f, 0.0f ) ), 0.0f );

if( Vector3.Distance( TRANSFORM.position, PATH.vectorPath[ CURRENT_WAYPOINT ] ) < NEXT_WAYPOINT_DISTANCE )
{ 
	CURRENT_WAYPOINT++; return; 
}
