The last thing the sport needs is a $600 failure. Stuff like this just happens and it's happened for the last 30 years. I mean, it's inexcusable, but the first runs on any new street track usually sees something no one could predict.
Completely throwing the spectators out and not letting them see a session they paid for is not good business. There wasn't enough security, so they really didn't have a choice. It's a bad deal for everyone, but they had better make sure the race goes on with no more delays if they want people to come back.
I think the best course would be to either hand out a pro-rated rebate to make up for it, or drag U2 back and have them put on a free concert. Something. They have to do something besides screw the paying spectators. Anyone remember the backlash from the 2005 USGP? `
For all the handwringing and discord, we still have a race ahead of us. Let's hope that goes well because we don't need this event to fail. If they can get through the rest of the weekend without another catastrophe I think they will be ok. After all, it's just practice, man. It's practice. Practice.
