return void wont work.

Java is not my strongest language, but I can identify a couple of issues that might help you figure out a solution.

  private int lapsDriven;
  public int drive() { // you'll want this to be void, rather than int
    lapsDriven++;
  }
  return void; // void methods don't need a return, and you shouldn't have a return statement outside on its own

I think your code looks good apart from those issues. But let me know if you still run into problems and we can figure it out together. :)

thanks
