3km/j on plus highway ?

On the way back from lumut, we decided to took Plus highway, out from Bidor toll heading back to KL. Once we out from Bidor toll and I was able to become a Formula 1 driver just for few minutes, then the 3km/j speed journey start...this is the worst jam i ever had ???? just a 20km distances but i had used about 5 hours to finished this journey. My God.... 5 hours jam....
