to the OP,
as you were back visiting your folks, these civic minded folks were in fact not spying on their neighbours, but in fact outsiders like yourself who abused their community by breaking the law and driving dangerously, putting the lives of the local community at risk.
It’s a bit sad that as a cyclist yourself, who really ought to have a good grasp of road safety issues, that you haven’t yet grown up enough to realise that you are in fact, just in the wrong, and you are in fact the reason that people feel the need to try an protect their community from the hazard that dangerous drivers are. Grow up.
I wonder, do you have kids?
If so, i suspect you might support the pointing of a very different kind of gun at drivers who speed, and definitely those that pass you at a junction whilst texting or blabbing away into their phone.
