28,694 Pointsit accepts the following. Lowering the count needs to happen after the test. THe test i uses is different to yours, as well.
public void drive(int laps) {
// Other driving code omitted for clarity purposes
if(laps > mBarsCount){
throw new IllegalArgumentException("Not enough battery remains");
}
mBarsCount -= laps;
}
