I don't watch Nascar, but yellow mustang was in a tough situation, being boxed out by 2 cars, bounced off a wall. He couldn't slow down, guy behind him. Bubba didn't give him much space to work with either.

It's motorsports, accidents happen, It doesn't look intentional to me.

There is a reason Bubba isn't a respected well-known driver. Hes not good at his craft.
