The track for the United States Grand Prix is sinking.  The track has sunk over 1 meter (over 3 feet).  The changes in the track are causing very bumpy places along the circuit.  At the start of Free Practice 1 (FP 1) Lewis Hamilton of Mercedes-AMG could be heard on the radio to his pits questioning the safety of the track.  To date, various parts of the track have been scrapped to try to get rid of the high areas being created by parts of the track sinking.  No doubt before next season’s race the track will need to be resurfaced.
