4 important things to consider when designing streets for people, not just cars

Go to any medieval European city and you will see what streets looked like before the advent of the car: lovely, small narrow lanes, intimate, and undisputedly human-scale. We have very few cities in the US where you can find streets like this. For the most part what you see is streets that have been designed with the car in mind—at a large scale for a fast speed. In my native San Francisco, we are making the streets safer for walking and biking by widening sidewalks, turning car lanes into bike lanes, and slowing down the cars.
