“Our cars are tanks now,” Bell said. “The Xfinity (Series) cars are a lot more fragile than what we have today. It just comes down to respect, and whenever you have respect in a race car and respect for your competitors, the outcome is a lot different. We want to be known as racers; We don’t want to be known as wreckers.”
