Parking warden whistles

I realise that these guys are not employed for their intellect, but a blind man can see that madly whistling at cars that are moving, or cars that cannot move does not help an any way with the flow of traffic. 
All it does is deafen people nearby.
For a taste, try the Chaeng Watthana road at the Government complex at 5PM on any week day or Seacon Square on a weekend or public holiday. The noise is painful at less than 50 metres and still annoying at over 100m. And it is completely pointless. It achieves nothing. 
I ask that you please remove whistles from all ‘security’ guards throughout the city.
And it would be in society’s best interests long term, if they were surgically altered so that they never reproduce.
