YANBU providing:
There's proper investment in functional affordable public transport for all the country not just London and a handful of other cities.
There's proper investment and appetite for home working where appropriate and people aren't made to go to offices daily because the bosses say so.
There's proper investment in safe cycling facilities and as a nation we knock this ridiculous culture of widespread hatred of cyclists.
They work out where all the electricity is going to come from because currently we don't have anywhere near enough.
They make electric cars far more affordable, so they're not just available to the most affluent.
Electric cars have a decent useful range of at least 3-400 miles.
There's far more car clubs so people can access an electric vehicle when they need it without having to own it.
There's probably more barriers, but they're the biggest I can think of off the top of my head.
Because otherwise a few well off people who can generally set their own working hours etc will be going about their daily business happily in their electric cars while the less affluent half of the population will be back in the Victorian era where they manage to go to work and have neither time or money for anything else.
