It's about strategy. Its not Tory, Labour, Brexit etc. Rail Freight should be a strategy, it was lost because it was cheaper to haul by road. Covid may well flip that back. We actually need a long term transport strategy that addresses the needs of the user and limits the ability of local government to push the problem on.
Its actually a culture of NIMBYsm in local government. It started under New Labour, possibly even before. Walking streets, traffic calming, parking zones, congestion charging. These are all strategies that discourage road users from "coming here". Well they have to go somewhere.
I suspect the return to work and end of lock down, has been the biggest catalyst. Consumption must have gone up recently.
