It's become a problem. We know it's a problem. Any solution that we look for, we have to make sure we don't make the cars less safe instead of more safe. That's the No. 1 thing ...

I think we'll ratchet up the research and get a lot more input, but I don't think it will happen before the Daytona 500.
