There's videos of fire trucks doing exactly this (one even to a police car that was blocking their way to a building on fire!). Fire trucks are made for stuff like that. Legally parked cars are the problem for whoever was blocking the road, not the fire truck. When there's an emergency, fire trucks have wide latitude to do whatever is necessary to get to the scene. They can't cause other crashes, but causing property damage for illegally-parked vehicles is fine.
