CAR LURCHES FORWARD WHEN BRAKES ARE APPLIED ON BUMPY OR UNEVEN SURFACES, AS WELL AS SLIPPERY SURFACES SUCH AS METAL PLATES THAT YOU SOMETIMES FIND COVERING CITY STREETS UNDER CONSTRUCTION. ON ICE, WHEN APPLIED FORCEFULLY, NO BRAKING ACTION OCCURS WHATSOEVER, EVEN WHEN PUMPED OR RELEASE AND REAPPLIED. IN JAN 2013, CAR SLID MORE THAN 150' ON A LIGHTLY SNOWY ROAD INTO A DITCH. MY SENSE IS ANTI-LOCK BRAKES ARE DEFECTIVE, BUT IT COULD BE SOME OTHER COMPUTER OVERRIDE THAT KICKS IN. WHEN STOPPING FOR A TRAFFIC LIGHT ON A BUMPY ROAD, OR OVER ONE OF THOSE CONSTRUCTION PLATES, IT'S SCARY, AND I FEEL LUCKY I HAVEN'T HIT ANYONE. *TR
