Here's my take from a guy with limited interest in motorsports. I live in Indy, so it's impossible to not get into it somewhat.
Many people seem to be painting a picture that the Vegas race was a financial disaster for F1. They sold the place out. Pricing plunging on the secondary market from astronomically high to high, and this change didn't cost F1 a penny. For some reason, many writers want to make this situation into a disaster, including making such an issue out of the track problem during the first practice day. They paint a picture of a poorly planned event. The situation was rectified, and the racing was outstanding. Stands were full.
It was a successful first event, and they will not have the same problem next year in practice. The iron cover, which was sucked out of the road, did not fail at the weld, but instead the hyper low pressure created by the car literally ripped the 12 inch iron cover right out of the concrete. They secured all similar water valve covers in quick set concrete and problem solved.
The race was great.
