We have the opportunity to give people and businesses in New Zealand real options, so that they aren't locked into using a car for every single trip they need to make. The opportunities there are that that's better for the climate but also that that costs them less. We have a transport system that at the moment where Government, if it's only investing in roads, it means that people have to have a car to get around, and they have to spend a lot of money on a car. They've got to spend a lot of money on fuel, and we have to use up a whole lot of land in our urban areas to park the cars, three-quarters of which is empty at any given time.
