NYC averages a population of 1400 people per city block with mixed use development. Pictured above in Houston they fit 126 cars per city block sized parking lot.
Oh, Houston has public transport, of course. It’s actually not bad if you live outside the city and work downtown. You can catch a commuter bus and they get to use the HOV lanes. But the city street buses? The city is just so huge that it takes two hours to equal a 30 minute drive.
