I think usac needs to change the way the don't like the start of a race other than just holding a green flag still waiting for them to see yellow lights on the back chute. I do think some drivers don't see them not waving the green. Hold the yellow in front of the green until you like the start. An old practice. Use two hands. Start them close to the starter not coming out of the turn. Over the years I have seen many a bad crash because of this practice. Or show them the yellow light in one if the start isn't to the starter's liking. I know, old school thinking
