Its a nice dream but unfortunately the cameras remain, and every car driven inside the M25 ring road gets checked. If you haven't logged on to TfL and registered your car, even if your car is compliant and doesn't need to pay any ULEZ charges, then you get fined. Any diesel cars older than 2016 are non-compliant which is why so many tradesmen are pissed. Godspeed to the Blade Runners. They're doing gods work, but for the sheer scale required to defeat this beast, it is not nearly enough.
