To really remove cars from the roads we need to reduce the need for one at all. Hyper-localism should become the ideology of the future, where not only is everything you need within a 20-minute walk of your home but things like energy generation are also done at neighbourhood-scale, either by installing renewables and batteries or just buyng it off of your neighbours or repurposed office blocks as vertical farmland.
The Victorian philanthropists of the past built communities for their workers around their factories; what we must build our workplaces around our own homes. Do you need everyone to be 'in an offce' 9-5 or just at crucial adjucts in a project? A meeting can be a walk around the local park or lunch in a pub as much as a boardroom.
