The more you densify a city, the more congestion will increase, however technology changes... cities so packed that they will no longer function... vertical sprawl.
Our intent will not be to create gridlock. Oh, except maybe from time to time.
I find it ironic how New York City Mayor Mike Bloomberg is so focused on such small issues as drink sizes, while ignoring the massive infrastructure challenges in New York - lousy roads, third-world airports, traffic jams, etc.
A good science fiction story should be able to predict not the automobile but the traffic jam.
We did such a great job of creating the interstate highway system in Oklahoma City that we don't have traffic congestion. You can actually get a speeding ticket during rush hour in the city. That's how great our traffic flows.
I take Sudafed to combat my congestion, so I always carry some with me because I like to be prepared and make sure I'm ready whenever symptoms strike. It's also a really good idea to figure out what your triggers are.
Portland doesn't have a 'sit-lie' ordinance like Seattle or San Francisco. Our use of high pedestrian zones is significantly more limited and nuanced, but it gives authorities the flexibility they need to address specific public safety or public health threats in congested areas, by keeping our sidewalks accessible and walkable.
If we didn't have Net neutrality, carriers could do things like penalize companies that use a lot of bandwidth or create high-speed lanes and charge Internet companies extra fees to send their stuff over them. That would give an advantage to big companies and make life harder for startups.
