This happens always for all kind of small items. Sharpened Stick, Rags, Spark Plug, etc. Especially annoying if it is a small items like the sharpenend stick, spark plug etc. that you don't see on the street while driving towards it.
The car will not just be stopped but totally crashed/shredded. Doors get ruined and fall off, tires are ruined, battery and spark plug are ruined. And even if you replace tires, battery and spark plug the engine won't start anymore.
