That's not what Geoff is saying. He says that the justification for ULEZwas air quality. He believes that the undisclosed aims were to raise money, like a London tax, and to discourage people from using their cars. The measured data shows no change in air quality since they expanded ULEZ, even though there are fewer and cleaner cars. To any statistician, the air quality, number of cars and type of cars are therefore independent variables. In that case, if the goal of ULEZ was air quality, it should now be abandoned and they should divert their efforts to find the actual cause.Your favourite twerp Geoff obviously doesn't think:
The congestion charge lowered central London motor traffic by 20%.
The scrappage scheme permanently got rid of a large number of the dirtiest diesel vehicles.
The LEZ and ULEZ zones have resulted in large numbers of other high emission diesels leaving London for much more distant parts.
Over 1400 of our buses are zero emission and that is rapidly increasing.
Over half of all our London cabs are battery electric driven now and zero emission capable.
Over 65,000 of our London cars and vans have no exhaust pipe now.
Private car ownership in London is now at an all time low.
National average annual car mileages are down 40% from those of fifty years ago.
And vehicle mileages per gallon have enormously increased over that same period.
Over a million of our national car fleet is now solely battery electric, with a further 600,000 hybrids.
Of course our pollution is down, enormously down.
.
Logic says that pollution should be down, but the data show's it isn't.
