I noticed this too. It seemed like a lot of people were having trouble with their launches as well. Maybe this was a product of poor track prep? The wait was pretty bad too. My first run early in the day went pretty quick but as the day went on the wait kept getting longer and longer even though the line didn't seem to get much longer, just the speed at which people were pulled through...

Despite all this I had a great time tho . Lots of cool cars dragging and great drift drivers!
