Haven’t RTFT, but if anyone has said that 20mph zones, ULEZ-type schemes and LTNs aren’t designed principally as a backdoor tax by permit pricing and penalties, they are profoundly naive.
Perhaps we should be taxed more. But if so, let’s be honest and transparent about it.
I don’t believe for a moment that air quality or safety is behind any of this.
And anyone saying that any decent driver can stay at or below 20mph without constantly having to check the speedometer is either not a driver or is knowingly perpetuating a falsehood.
