TRACTION CONTROL CAN SNAP THE DRIVERS NECK. WITH TRACTION CONTROL ON THE VEHICLE CAN APPLY THE BRAKE ON THE DRIVE WHEEL THAT IS SPINNING. THIS HAPPENING IF YOU ARE NOT GOING IN A STRAIGHT LINE CAN SNAP YOUR NECK IF DRIVER IS NOT LOOKING STRAIGHT AHEAD. NOTE WHEN THE BRAKE IS APPLIED IT IS NOT SLOWLY, IT IS SNAPPED ON, THIS IS PAINFUL AND COULD KILL. PLUS I DO NOT THINK THE DRIVE-LINE PARTS WILL LAST VERY LONG. ALSO I WOULD LIKE A WAY TO MAKE SURE THE SYSTEM WILL NOT 'COME ON' BY DEFAULT. WHEN THIS HAPPENED TO ME I WAS PULLING OUT FROM A STOP MAKING A LEFT HAND TURN AND THE INNER WHEEL SPUN ON THE WET PAVEMENT, THE 'SYSTEM' APPLIED THE BRAKE WHILE I WAS LOOKING LEFT AND MY NECK WAS TWISTED MORE TO THE LEFT THEN RIGHT FORWARD DISPLACING MY NECK. NOTE 'TRACTION CONTROL' IS DEADLY !
