Outside of the greater Manchester caz could be well over fifty miles away.You can't seriously be saying that the level of pollution wouldn't make any difference to a child with existing breathing difficulties. I have a vested interest, having COPD to the extent I have just been prescribed oxygen. For some time now I can tell if the surrounding air is polluted to the extent that it effects my breathing. People seem to be saying that their right to drive what they want where they want should supersede the rights of those with respiratory problems to live as normal a life as possible. My grandsons live very close to a major southern approach to Greater London, which is busy 12/14 hours a day. I frequently notice fume laden air there to the extent that I occasionally wore a mask prior to covid.
I am sympathetic to owners of vehicles which are classed as high polluting, but there are solutions, including storage outside a CAZ
Then all you would be doing is using the pollution making vehicles elsewhere, causing problems for others. The caz is all about making money, by charging people it will not make the air clean, if they were serious about it they would ban the bad vehicles, but no as long as you pay you can use them.
As the motorways are not included you can drive a very polluting vehicle through the caz area as long as you don’t leave the motorway, but if your a foreign registered hgv’s you can go anywhere you like as they are exempt, same as council owned vehicles, no matter how bad they may be they are exempt. It’s just a complete farce.
