This is neither here nor there, since street parking in SF is probably much too cheap now. But doublespeak is doublespeak.
Didn't some company used to have a marketplace for public utilities? Remind me how that worked out for California?
With sensors and networking becoming a commodity, I have a feeling these realtime marketplaces are going to start popping up in industries nobody really expects.
The only way that parking would, in general, cost a whole lot more in the future was if there was a whole lot more demand - and I'm not sure anyone is predicting that we are facing an imminent increase in the number of cars seeking to park in San Francisco.
