As you are aware, once the rear tires break traction, it really doesn't take much to spin out, or loose control of the car if you are not ready for it. It really isn't as much as a problem in front wheel drive cars as the front tires spinning, doesn't cause you to spin. Also most cars do connect to trans to get speed, but I can tell you that a 1976 Mercury Monarch does not. The speedometer cable is connected to the transmission, but the speed sensor that the cruise control used was connected to the left front wheel.
Edit: With most cars now using electronics to send speed data (My Mustang has a speedometer cable that turns an electronic speed sensor mostly for the purpose of having a cable I believe) I would assume that the source is the same for all speed sensing. So it may not be as bad as it used to be. I just have never changed my driving habits.
