The footage is from the fisheye lens of a dash cam, so the fireball appeared larger in person. I was driving past mile marker 95 on I64 East through Indiana.

Remarks
The fireball flashed to about 3 times its original size and became much more blue for a split second. I'm not sure if I saw any clear fragmentation, but the fireball appeared more like a club or clover than a sphere. My guess is that fragmentation caused this abnormal shape.
