Zack Ryder used to be entertaining. After his run got halt, he has lost passion and the will to wrestle. It's pretty obvious. Now his skits are half hearted. He's just doing them for the sake of doing them.
His character is supposed to be the People's champ (in a way) and is pissed that they are not respecting him afor doing so, so if he brings out the cars it won't make any sense that he's fighting the good fight for the people (as a heel though)
