Funny you've said this. After reading some topics on this forum and seeing some videos on Youtube I can't help thinking that the rise of dashcams gave powers to an army of self-righteous twats who have nothing else in their empty lives but to complain about irregularities of others.
Someone changed lane without indicating? An army of wannabe crucifiers is out in full force.
Seeing someone overspeeding by 5 mph? Ohmygawd, this is a potential child killer out there - punish him/her now!
Did they undertake you when you were steadily driving 40mph in middle lane? Hang, drawn and quarter them! Now!
And so on and on and on.
I think if they would be given enough powers, some fellow citizens will do their best to turn society into Brazil-styled one (this is not the name of a country but rather the movie title - watch it, it is very powerful).
We don't even need to turn the country into aristocracy-driven police state - the ordinary citizens will be the police, judge and the executioner, all in one, just because their self-righteousness will tell them that they are the most moral people on the planet. These moral beacons will then try to force their view of society rules upon the rest of us (just what Grauniad, Independent and Daily Mail are doing).
I mean, dash cams are useful tools when dealing with road issues but is it really necessary to post videos each time someone made a slightly illegal maneuver?
Rant over.
