It happens really fast, but to my eyes, Chase starts to turn before he makes contact with the 11 and 6 cars. Seems obvious to me. But I guess Nascar will have to use their own data.
To me, if they don't suspend Chase, it does two things. One, they play favorites, and two, it's saying there are no consequences for reckless racing unless you're certain drivers, which I guess is still playing favorites. I feel like drivers will continue being too aggressive if they don't do anything about it.
