I was on I-35 NB and had my CC set for the prior several minutes. i was traveling uphill and was buffeted by the wind from an 18 wheeler and the CC just shut down as if i had hit the brakes. I know i did not accidentally hit the brakes, so save that one! :P the lack of accelerator and decreasing speed caught me by suprise and it took me a second to figure out what happened.
Anyone else seen this before?
