That said with a tool like that wouldn't the # of parking tickets issue by any city go down and thus they would have an incentive not to allow such a tool to be widely deployed?
I swear that parking signs are deliberately put up to confuse people so they can get more revenue!
Of course we know the real reason is $$$. But if we take them at their word, providing access to this data would help them achieve their goal by helping motorists park properly and legally.
I can imagine, too, this would be incredibly useful if self-driving cars ever become a reality (or in helping them become a reality). After one drops you off at the show downtown, it could then check for nearby parking. But maybe this is dreaming too far down the road...
