The ASC will quickly realize that that math for the 4 wheel speeds doesn't match a normal corner speed and intervene on 1 or more wheels.
So yes, if you are going straight, even if the ASC is on, all tires will likely rotate the same speed unless the Toe on the front wheels is so far off that your are (literally) scrubbing the entire (front) tire off and front and rear speeds differ too much.
Get your tie rods fixed and it should just go away. Also, some of the professional damage repair services will rectify any bent A-arms and struts to get your alignment back.
Do this or you'll just write off front tires in the space of month.
Thanks databeestge, I guess there is more to it than just monitoring wheel speeds, since wheels speed are different during cornering. The computer must have a map of the anticipated speed variation. I also got a bunch of warning lights coming the hill last night: RBS, !, ASC ...
