Like the idea but are the efforts wasted when they are not enforced? Here in Newport majority of speed camera’s simply display the speed for the driver. On Stow hill where I live when the road isn’t bumber to bumper cars are regular passing thru at 40+ mph in the 30 zone, with several daily even exceeding this! I have even seen buses and taxis exceeding limits and as they’re livelihood at risk if caught seems they are not concerned by either consequences or actual enforcement.
