Traction Control

Drove to Eugene yesterday to see the kids. Horrible, terrible, very bad rain storm on the way home last night. It was so bad I actually was driving below the speed limit, something I have never willing done before. As it my habit, I used the cruise control. A couple of times I felt the car suddenly slow down, like I had run into some deep water, but the car didn't resume it's speed after I imagined we had cleared the puddle. What I think happened is the front driving wheels lost traction for a second and the traction control detected this and disengaged the cruise control. Curious. I had never run into this before.
