A normal car may be quiet but the noise coming from the tires against the road will make more noise than the engine. Plus since this particular incident is on a bridge, there's also the added noise of the tires going over those bridge sections that I'm sure all of us hear every few meters when driving over a bridge. And what if a bus or truck drove past as the test was conducted?
