Though not a new idea, its sanity level, or lack thereof, remains the same: permanently removing vehicles and Muni lines from Market Street. This is the latest idea tinkering around inside Newsom's sleek head.

SF Examiner reports:

The City is in the midst of a six-month trial that aims at limiting the amount of private automobiles on the major thoroughfare, and the mayor says that if the data backs it up, he favors an expansion of the vehicle ban — and also moving toward removing Muni from the street.

According to Curbed, this means a "ban on all cars ... and remove all the Muni lines, including the F-Market" from Market Street. This would free up San Francisco main thoroughfare for things like small boutiques, art, increased pedestrians, carriage horses, singing children, and other springtime-in-Paris moments.

But Newsom's idea may not be that nutso. All of the car traffic and Muni lines would then shift over to Mission Street. Could Mission Street, in its current condition, handle all of that traffic? No, no it could nice. But still, a car-free Market Street, would sure be pretty. And that's about it.
