Improved public transit and proper bike lanes would be nice to see in my city.
WA has a lot of bikers but a lot of them seem to think they own the fucking road. They'll become pedestrians or road vehicles whenever they need to. To all would-be bikers: If you ever make the decision to ride a bike around, don't be a dick about it and swerve in front of everyone else's car.
This kind of thing, as well as the drivers who act like idiots around bikers, is part of why I'd like to see bike lanes become standard for roads.
Seattle is a public transit nightmare because of its hourglass shape. There's a bottleneck at the bridge, and lots of people who need to get across. From what I understand, they're trying to encourage people to use the bus by putting insanely high tolls on the bridge.
Here in Calgary, one of the biggest issues is urban sprawl, and the public transit system has struggled to keep up as a result. Add to that the fact that we're in bad need of c-train expansion, particularly in the south. Here's a map of the current legs:
