A telling quote in the article came from Boston Mayor Marty Walsh: fees can't be so high that "people are discouraged from parking". Hmm, does this mean there would be too many available spaces? If that were the case the City would simply lower the price. That's pretty straight forward no? It's almost as if he's saying: If we raise the price to high, our hands may be tied and we won't be able to lower it? If the City is earnest about parking reform they will lower the prices and even turn meters off when there's no demand.
