City roads should be ‘ripped out completely’ to fight pollution, says government adviser
(www.telegraph.co.uk)
This is a fantasy. It can't be implemented in large scale in any practical sense.
Centralization of distribution and centralization of production is always more efficient. You aren't going to put dairy farms next to apartment buildings next to orchards next to paper manufacturing plants next to microchip fabricators next to restaurants next to family homes next to waste water treatment next to hospitals next to bookstores next to power generators next to garbage incinerators next to grocery stores...
These things get separated from each other for good reason, and running rail lines to all of them will never be practical. There will always be a need to fill the gap with small, independently powered vehicles for cargo transport.
