Should you flash? well to take this issue one step further, from a utilitarian perspective if its for the greater good for the greatest amount of people aka benefit them then I say it is valid. I personally would help a fellow person out my giving them a heads up about a cop because by doing so I am helping someone avoid a heavy fine.Then again if someone comes flying by at 75 on a two lane road they may not even be paying attention to me trying to help them out. Also when you are driving a car, it is YOUR responsibility to make sure you follow the law, so inspite of someone trying to help, people may choose to still speed and eventually get caught. So as a person, you can do your part to help a fellow person out even if its against the law, whether it is right or wrong depends on whether you are willing to look at it from a "greater good" perspective or not.
