Above is a case as to why Indycar needs to do a better job of evaluating the venues they race at. Although it wasn't because of safety, last minute changes at Baltimore that was previously overlooked by Indycar delayed the weekend. Also the ingural race at Sau Paulo had major problems with slick concrete on the front straight. All in all, Indycar must do a better job of inspection before they race weekend gets there.
Here is a list of acceptable ovals that Indycar has a realistic chance of running on. Some of them in there are current ovals arlready on the schedule (bolded). Of course, this is just my opinion. Factors that influence my judgement includes length of track, banking, and geographical location:
Now I don't know about all y'all, but that is a lot of ovals out there. And if the car is getting better and if the airbox is going away (which will make the cars faster), we as racing fans have a lot to look forward to. Don't worry fans, time to just wait and see.
