They'll have to take public transport. Modal shift is something that governments have constantly blathered on about. Forcing people out of private cars and onto buses and trains.
Let me guess - do you live in a city by any chance?
Meanwhile, and in the real world...
Our farm is 4..5 miles from the nearest village, where the bus stop is.
No buses after 8.p.m weekdays, no buses at all on Sundays.
Even if the private bus Company wanted to run a service near to our farm, the roads aren't wide enough for them..
So, everyone needs their own transport, and not just any transport, because in the winter they need a very capable 4WD car. These cars use a lot of fuel and they do pollute, but the vast majority of people living in rural areas can't afford a new, low emissions 4x4.
And even if they could, the roads aren't wide enough for 2 cars to pass, without usually scraping against hedges, not something that most people want to do in shiny new cars.
