The __ in four-wheel steering operates independently of the steering wheel and driver input. a. Active system b. Passive system c. Involved system d. Motion-controlle system

## Step 1<br />The problem is asking us to identify the type of system in four-wheel steering that operates independently of the steering wheel and driver input. <br /><br />## Step 2<br />The options provided are: Active system, Passive system, Involved system, and Motion-controlled system. <br /><br />## Step 3<br />An active system is one that operates independently of the steering wheel and driver input. This means that the system can make decisions and take actions based on its own programming, without needing any input from the driver. <br /><br />## Step 4<br />On the other hand, a passive system requires some form of input from the driver. This could be a physical action or a command. <br /><br />## Step 5<br />The terms "Involved system" and "Motion-controlled system" are not standard terms used in the context of four-wheel steering systems.
