It will be interesting to see the way it was set to go off. For effectiveness it is usually something to do with the movement or action of the car. One in Porto Rico was a trembler switch, so was one against a medical tool company in New York, often found when looked for, but they can be effective. The other activation is remote control, such as the Orlando Letelier device set off in Washington DC, which once again was very visible if looked for. When you see muck ups like this one, normally someone tried a timer, or we will see something hit the car hard enough to set the trembler switch off. Biggest defense look for it, a 25 dollar inspection mirror with a flash light works well.
