Over on Streetsblog, commenter ChipSeal writes, "Why not eliminate curbside parking and open up the public space for all road users?"
Why not indeed! If cars are bad, why provide any space for them? If it's good to make it a little more difficult for people to drive, why not make it a lot more difficult?
In the long run, that's true. The less you accommodate cars, the better. The problem is that people often hit parked cars with their own cars. If the cars aren't there, they often go up on the sidewalk. It all depends on how fast the cars are going. Below 15 miles per hour, it's probably safe for pedestrians and cars to mix, but above that I think that curbside parking improves street safety.
Of course, there's still every reason to replace curbside parking with other uses, such as loading zones, bicycle parking and bus bulbs. And it's a good idea to reduce the overall amount of parking, which can be done by reducing off-street parking. But eliminating large amounts of curbside parking is not a good idea when cars are going fast.
