I hate when a real car accident is attributed to a drunk driver when it was not. There are plenty of wrecked cars from actual drunk driving, you don't need to lie to get an example. Some people think their intentions justify their actions, even when their actions can accurately be described as "lie" or "cheat" or "for profit" or some other dishonest thing. This may be effective in many cases, but in others it discredits your efforts and perhaps even your cause.
Random acts of kindness DO happen, but are usually not captured on video.
