Exactly correct, ULEZ and LTNs have created a mess in London. These policies are driven by socialism not environmentalism. Climate is the excuse, reduced personal freedom is the intent. Thankfully many citizens in the EU and UK are waking up to it, so I hope a lot of these authoritarian policies get reversed in the future.
