I am thinking of starting my own vigilante corps.
1: to the old couple who crossed the road yards from the pedestrian crossing (while their light was red) and caused a motorbike to screech to a halt, nearly getting themselves knocked over in the process because they didn't heed the rules of the road and didn't even care when I told them off for it
2: to the countless knobheads who stop over the pedestrian crossing because the traffic has backed up at the crossroad lights.
3: to the van drivers who park their vans half on the pavement by my shop, causing a hazard to all people with buggies/prams/wheelchairs.
4: to the Carer who parks on a single yellow line immediately as the restriction comes into force, and not only that, opposite a junction (which road doesn't have parking restrictions and would mean a 10 yard further walk to the house she's at) - when I pointed it out she used the excuse "I'm caring for an elderly lady" (I'm sorry, I didn't read that bit in the Highway Code that said you could break two Highway Codes rules in one hit if you were caring for an elderly lady
)
4: to the lady who parked in the Disabled Bay because it was after 6, and after having it pointed out to her (in case she hadn't noticed the road markings), she said in front of her 10-year old child that she didn't care.
Feel free to add your own.
