One more thing. Don't you see an irony in a supposedly forward-looking, progressive city like San Francisco clinging to subsidies for an inefficient, polluting relic of the 20th Century called the personal passenger automobile? In a densely populated city like that you'd think they'd be charging more for parking (by selling permits and increasing meter rates to reflect market realities) to subsidize trolley and bus tickets. Then the need for phone apps like MonkeyParking wouldn't be nearly as urgent. And wouldn't that solution be better for the planet?
