A new camera was just put up at Ave I on Ocean Parkway and it is to catch speeders,southbound across from the Lubavitch Yeshiva. Besides for the police who sometimes wait near Ave K like Thursday this week using laser.
If the purpose of the light is to prevent speeding, then the OP was helping the cause. Why are you bothered?
If that is not the purpose of the camera, they what reason is there for the city, or whoever is operating it, to put one there? Is it another tax? Then again the OP is presenting a legal way to avoid being subject to that tax.
The purpose is to save someone aggravation from making a mistake and also to give people a reason to follow the law and drive slower. No one says speed elsewhere, save yourself money and maybe even sholom bayis.
