Attempted to overtake us on A47 roundabout, by approaching at high speed from outside lane with only single carriageway exit, braked excessively skidding onto the roundabout and forced our car to avoid the collision, basically out of control with wheels locked up. Totally reckless with no advantage from the mad maneuver we were all behind several slow lorries. He was obviously not willing to wait. Not much fun for me as a passenger, had just had an operation and was coming home and did not need this idiot!
Van had painted rear window so could not see driver.
