Just rode Test Track once and it was much faster than I remember! Not as imaginative as Radiator Springs Racers, but more thrilling.
Then DBIL, DD7, and I were using our RS pass and it broke down just as we were starting to go up the first hill. 
We were evacuated and got a fastpass to any attraction at Epcot today except Frozen. (Double facepalm.) I’m doubting we will get any use out of that fast pass.
