Whether or not she was targeted, her car definitely was.
Had someone lit a slow match and tossed the device under the car, I would be willing to assume vandalism and a non-specific target.
But rigging a wire to activate a detonator when the car moves is definitely targeting the car and its driver.
The law presumes that a perpetrator intends the ordinary and forseeable consequences of his act. It is ordinary and forseeable that the next person to move that car would be its owner or a member of her family.
I wonder if some criminal has it in for that family for some reason. I also wonder if perhaps they were random victims of Islamist "students" who are practicing their bomb-making art.
When an *innocent* victim is targeted that is terrorism. Or this could be a test by someone to check on their design to see what the effectiveness is. Perhaps this car was *tested* because of its location or availability. Or perhaps it was meant as a warning for someone else who lives in the vicinity. Or ..... and the list goes on and on.
