Impressive (Anti-) Demonstration of Traction Control Systems

I thought the season was over -- the season of pulling people out of the river at my campground. But a rear-wheel-drive Ford Transit van got stuck just after its drive-wheels hit the water. It's true that he chose the wrong place to cross. Remembering what I learned from experimenting with a Nissan NV van a couple years ago, I told him to turn off the traction control switch on the dashboard. Naturally he had no notion what that meant. But he finally found the switch. By turning off that switch, the traction control system was supposed to surrender its capability to throttle back/down the engine when a wheel starts slipping.

But that isn't what happened in practice, with the Ford Transit van in the river, where one wheel still slipped, while the other was completely stationary -- just the malaise of an open differential, in olden times. All this occurred in rever

What kind of life had they had together? And now it was winding down.   Perhaps the reader has seen that wonderful new movie directed by Lasse Hallström, "A Dog's Purpose." In the movie, a dog lives with his humans for awhile, ages or dies, and is reinca
