Java Java Objects (Retired) Harnessing the Power of Objects Method Signatures

What could I be doing wrong?

Prompt: I have added a method drive that defines a parameter laps. These high-powered GoKarts use 1 energy bar off their battery each lap. Using method signatures, add a new method called drive that performs just 1 lap and takes no arguments.

GoKart.java
public class GoKart {
  public static final int MAX_BARS = 8;
  private String mColor;
  private int mBarsCount;

  public GoKart(String color) {
    mColor = color;
    mBarsCount = 0;
  }

  public String getColor() {
    return mColor;
  }

  public void drive(int laps) {
    // Other driving code omitted for clarity purposes
    mBarsCount -= laps;
  }

  public void drive(){
   GoKart.drive(1); 
  }

  public void charge() {
    while (!isFullyCharged()) {
      mBarsCount++;
    }
  }

  public boolean isBatteryEmpty() {
    return mBarsCount == 0;
  }

  public boolean isFullyCharged() {
    return mBarsCount == MAX_BARS;
  }

}

Figured it out. Instead of doing

GoKart.drive(1), I just do drive(1).
