Hmmm. Don't drive much on snow and ice do you? When coming down a hill with a stop at the bottom, you really want to come to a complete stop at the bottom. You don't want to smack into whatever traffic may be out on the road you are stopping for. Especially if it is a snow plow. And you'd like to keep the car on it's normal side of the road pointed in the conventional direction. Safer that way. The best way to accomplish that seems to be to be to lock all four wheels and use the steering to control direction while the vehicle slowly slithers to a stop. Except that doesn't work with ABS. Don't believe me? You're welcome to try the hill opposite my driveway come our next big snowstorm -- probably in a few months, but in Northern New England, one never knows.
Maybe it's old primitive ABS that's a problem. Well, the Camry I drive IS 16 years old. But my wife's two year old Hyundai does the same thing.
Not what you've been told? Let me let you in on a secret laddie. Marketing people sometimes misrepresent (i.e. lie about) vehicle capabilities. Since they are rewarded for doing so, I suspect it is unlikely they will change their ways any time soon. (Actually, it's been well known for decades that ABS works well on dry roads and OK on wet ones, not too well on dirt and poorly on ice,snow, gravel)
