Noticed in the past one could not rock the car back and forth to get out of a snow drift because the engine wouldn't respond. Recently started up a gentle hill on a city street with heavy traffic. Tried to get a run but accelerator was unresponsive. While trying to get up the hill the engine backed off to idle with the gas floored. Cars behind almost hit me, and were very upset for obstruction of traffic. This is precisely a Ford problem. Traction Control aught to be an on off switch not a 7 step menu process. One should be able to turn it off permanently rather it resetting to on when you restart the car. This creates an unsafe and hazardous condition when the roads are at their worst. The designers that came up with this control philosophy aught to have their thinking rearranged. If I was the engineering manager heads would roll.

Update from Dec 15, 2016: The default position of traction control should be last position. That is if one turns it off it should stay off and not come back on when restarting the vehicle. Cannot emphasize enough that TC is unsafe in heavy traffic.
