System Could Save 7,000 Lives a Year

Just think how many lives we could save if we banned cars like Al Gore wanted to do?

"How does what you described differ from the traction control that Ford used on several models that can detect a spinning wheel and apply the brake to that wheel to transfer power to the other wheel, as well as to cut back on the throttle?"

Well, first of all, brakes are individually applied by the system on all four wheels, not just the driving wheels. Second, the system actually monitors the motion and attitude of the car (vehicle speed, individual wheel speeds, yaw rate etc.) while comparing it against position of the steering wheel. Conventional traction control only analyzes forces longitudal to the vehicle's long axis; full stability control also considers the lateral forces. In other words, traction control is only part of the stability system.

Here's a safety device to save twice that many lives...when you are driving a vehicle, any vehicle, concentrate on DRIVING only.

I see. Traction control seems to be most helpful (my car has it) in the snow where the function of transferring power from the spinning wheel to the one with grip can keep the car from getting stuck.

In fact, last winter my driveway with a slight uphill incline had 2 or 3 inches of snow on it, I had no problem driving up it. The traction control was working quite a bit when I did that.

Also try looking more than 50 feet in front of you. Pretend you're speeding and looking for cops. That'll work wonders to keep you out of trouble.

Problem is that people don't bother to learn how to drive anymore and the cars are so smooth it seems like they drive themselves.
