Read this article. Neat huh! What's wrong with this?..at the moment I see nothing...but, of course, the expense of installing sensors in every parking place and of laying out street with designated parking places...neither of which New York does.

But if such a service had existed in the 90s then we never would have had Seinfeld since many episodes were based on New York parking stories.
