Guys Guys relax. These pictures prove nothing. Unless we are given some true scenerio. If the city was parked then even the rear beams would have shattered due to transfer of the total impact of a car moving up to the a speed of atleast 60kph [which we can assume by considering the damage] Otherwise if City has braked hard then again the brakes of corolla are to be blamed and the poor safety standards of city are the culprits too as mentioned by mani.
But the matter of fact is "We know nothing" thus lets just pray for the owners to these cars to recover from their loss soon.
