Thank you Rodney for your post. This was not to put WKC in a bad position, but to alert racers that they themselves need to look at safety issues at the events they attend.
No matter how the track goes, there is no reason to have a vehicle exposed as it is in this video. Daytona KartWeek is another, where they have a vehicle sitting out on the long back straight that the corner worker used to drive out there. That should be behind the wall.
Sprint tracks have a number of fencing or other obstacles exposed all over the country, and its the racers responsibility to bring this to the attention of all the other racers. You can never be too safe.
