Joni Balter is actually making sense:

Bicyclists, runners, pedestrians and motorists share limited space and a grim truth: One wrong move and your life changes forever. It's dangerous out there so we all have to do a better job divvying up the pathways and roadways. Motorized or wheeled road hogs hurt everyone.

Whether we like it or not, urban travel has reached a point of congestion and competition for space from which we can never return. So let's make it work. Park those tempers at home.

I am not an advocate for any group because I drive, run and bike at different times. When cycling, I want drivers to slow down. When driving, I want bikers to refrain from darting out of nowhere in front of my car. When running, I just want to complete the run. No clear assumptions about who owns the road. That bright idea about making eye contact with a driver that smart pedestrians employ when crossing streets applies as surely in byplay with a bicycle.

Streetsblog cites the European model of road use: "Make cars, buy cars, just don't drive them all the time." And GOOD has an inspiring before-and-after graphic of a street in Manhattan that was improved to improve mobility and safety for all users, not just cars.* "It's easy to forget that our streets are alterable," the authors write.
