All those streets were repaved and manholes adjusted (or should have been) prior to the repave. The engineering firm (or I guess Clark County / City of Vegas Public Works) should have had documentation where each and every structure was located.
On top of that, F1, *at a minimum* should have had a walk through of the track the day prior to activity with a contractor on hand for last minute issues like this to be resolved.
If this is F1's deal (as I've seen) and they don't have a middle man putting this event on, this is 100% on F1.
What's embarrassing is that the NASCAR race in Chicago was commended for not having issues like this when I could d*mn well see clear as day dur8ng the broadcast there were structures and other imperfections where the contractor took shortcuts or structures weren't adjusted correctly.
I assumed an F1 track was surveyed with lasers and then graded flat to the Planck scale. It never occurred to me they would even allow disturbances to the plane like manholes or drain pipes -- but that all of that was taken care of off the track. I just assumed even a street race meant the entire length of the race the roads were hyper-engineered so you could drive those fragile little show ponies over them at eleventy-billion kpm (6.83508311 billion mph).
