Gary, No in answer to your question. That being said though here is some comfortaing news.
The actual time that the cars will be close to each other on the track is very very small. So that minimizes the chances of the cars getting together.
The other thing, is by the time your boy leaves in the dragster, the other car will be mostly down the track. If something is going to go wrong, there is a very good chance it will happen before you son even leaves.
I don't see it as a big dangerous deal. He will be fine. If you are worried about him, get him a fuel altered!
