This car (as well as several other sports cars) comes with high performance tires with so little traction in rain and snow that they totally defeat the purpose of the anti-lock brakes and stability control systems. these tires are so smooth that they will hydro-plane at 30 mph during a hard rain. in only inch of snow, the anti-lock brakes and stability control systems do not work at all do to the total absence of traction. above 5 mph in inch of snow there is no steering control as there is not enough traction. what is the purpose of mandating anti-lock brakes and stability control when you let manufacturers put tires on the car that defeat them in ordinary driving conditions? rain and snow are normal driving conditions in most of the us. the cad comes with a heated windshield, heating seats, heated steering wheel, heated side mirrors and a winter driving mode for the transmission, all indicating that this car is made for winter driving, yet it is totally unsafe to drive in the winter. the tires are intended to be safe at 155 mph (the car's max speed), yet there is no state in the country with speed limits within 70 mph of that. how does this make any sense? most consumers drive far more often in rain and snow than we do at 150 mph in perfect conditions. please mandate safe tires on new cars. i lost control of the car several times on grades as low a 1% and in trying to turn corners with only inch of snow on the ground. i had to stop driving it all winter. *tr
