Professor Edgar Morgenroth:

The really big issue is that we tend to separate various policy areas when they are actually connected. We separate transport from other planning decisions. We separate our sustainability from other issues. We separate everything neatly.

That is the biggest problem with this. I understand why people do not necessarily want to live in high-density areas if we do not plan our cities to be attractive. They then want to move out because they want a certain type of lifestyle and we accommodate that. Instead, we need to think about how we make urban areas attractive for people to ensure they never want to be out there and travel for hours to work. That is the big crux.
