So now, there is land being "unlocked" all over the country for new housing by the construction of lots of new roads. This will make a lot of money for the landowners but will lock the new residents of this housing into car-dependency and long commute times for generations to come.
It will also increase traffic congestion in the towns and cities where the roads are being built and therefore have knock on implications for existing residents.
But still we continue to elect these politicians.
