This challenge is looking for a specific incrementing technique to be used which is this:

public void drive(){
    lapsDriven++;
}

Adding ++ after a variable name will increase it by one. That is what the task refers to when it mentions "the incrementing shorthand" which it requires you to use.

Hi there,

If task 1 isn't showing as completed either there was a minor error in the previous task or something in the corresponding task has caused it to fail.

What you've written is technically correct but there's another way of incrementing the value that the challenge wants you to do.

You need to use the shorthand post increment operator

lapsDriven++ to pass this task.
