I'd like to add one...

Parking - The "invisible" link between land use and transportation is parking. It is the interface between the two and for 99% of auto trips it is "free" at the end. In reality americans spend somewhere between $150-$300 Billion a year on it. Most of it is payed through mortgages, property taxes, retail purchases, and whatnot. Getting rid of zoning laws that require parking and then even using fees to cover their cost would go a long way to changing the develoment patterns of our cities, suburbs, exurbs, and towns.

Absolutely. Ten, maybe twenty years ago Portland decided to stop subsidizing driving and emphasize mass transit. They now have an excellent "streetcar" system and thriving downtown... Constrasted to Kansas City, a city of like size, whose center is dominated by parking garages and open lots, suffocating all hope for a denser, more efficient lifestyle.
