Martinod I am far from perfect but you are looking at this from the point of making one mistake. Obviously a mistake can still kill or injure someone but there are many drivers who are reckless day after day.
If you make a mistake and there are no consequences then no one will send footage of that to the police, however if you make a mistake and damage is done, you are still responsible for it.
Would I like someone to send footage of something I did wrong, absolutely not, but that doesn’t mean its the wrong thing to do.
