The joke is people are that stupid that they don't know or care that you can see they are online and even when they are texting, however it works in our favour because if there is an accident or someone is injured on site, the phone can be used as evidence against that person.
That's the reason why I now always drive with a car cam so that I have evidence in case of an accident. The SUV's and expensive cars with no number plates and dark tinted windows so that you cannot see the occupants is a risk to every law abiding citizen. These are gangsters who will shoot you without blinking an eye.
