Well first off he isn't running over the bike, the bike is flying of the car. Secondly, they are still racing, just because the bike is off the ground means nothing, since the car also seems to be in the middle of wrecking.
Anyways, you could of disagreed in a more polite sorta way, instead of calling somebody else's shot "lame". That's very disrespectful. You could just as easily of said, "DO, I don't think your shot quite fits the theme given for this week". But whatever, the choice was yours to express your concerns, I've heard you out, and have decided to let the shot stay in since no one else seems to have a problem with it.
