Speed breakers on Lahore Ring Road

I had earlier blogged about the dangerous U-turns on Lahore Ring Road. Yesterday, during the trip to Namal College, I noticed something else. This time, unlike my previous outings on the Ring Road (on my way to Sialkot), we did not get off the Ring Road near the Ravi bridge to head on to GT Road. Instead, we went on towards the Motorway. We were obviously travelling fast when all of a sudden the driver noticed a speed breaker. He braked hard and managed to avoid a dangerous take off. We noticed several speed breakers along the way on our return trip at night. Wouldn't these cause road safety issues? I know that otherwise pedestrians would be endangered, but they aren't using the overhead pedestrian walkways anyway, and not adhering to crossing the road near the speed breaker.
