3,005 PointsR U sure you threw the IllegalArgumentException if the requested amount of laps would make the battery less than zero?
public void drive() {
drive(1);
}
public void drive(int laps) {
mBarsCount -= laps;
// Other driving code omitted for clarity purposes
int leftOver = mBarsCount - laps;
if (leftOver > mBarsCount) {
throw new IllegalArgumentException ("Not enough battery remains");

56,413 PointsIn this challenge the important this is: Check before you Act.
Also double check your condition, 1) you may not need the extra variable. 2) since you subtract from mBarsCount for leftOver, it can never be greater than mBarsCount (unless you drive a negative number of laps, which I suppose is something else that should be checked for but doesn't have to be for the challenge).
