Another in a long line of SFMTA measures restricting large vehicles from parking overnight on certain San Francisco streets was approved on Tuesday, this time focusing on the Marina. The Examiner reports that the rules, which effect vehicles over 22 feet long and 7 feet tall, are specifically designed to address a safety hazard some residents allege is caused by people living in their cars.

The ban prohibits parking on specific Marina streets from 12:00 a.m. to 6:00 a.m., and has homeless activists crying foul. "We are very concerned about the possibility of expanding this failed strategy," the Coalition on Homelessness's Kelley Cutler told the paper.

The "failed strategy" she refers to is that overnight parking bans on oversized vehicles were first implemented in 2012, and yet we still obviously have people living in their cars. As the bans only apply in certain areas, critics on both sides allege they only serve to drive RV-dwellers from one neighborhood to the next.

Perhaps in response to those criticisms, the SFMTA is now floating a scaled down version of an idea first proposed earlier this year by then "homeless czar" Sam Dodge. SFMTA senior analyst Andy Thornley told the Ex that one possible solution to the perceived problem of people living in cars would be to identify vacant lots and allow parking overnight in those spaces. However, in Thornley's mind, each morning the RVs would need to head back out on the streets to find parking for the day — likely an extremely time consuming affair as anyone who has every tried to park a truck in the city can attest.

At this point Thornley's idea is just that, an idea, and no apparent moves are being made to make it a reality. Interestingly, however, this may be the last new ban on overnight parking we see for a while. Gwyneth Borden, who sits on the SFMTA board of directors, said that she will not approve any additional overnight restrictions. “We won’t be entertaining these issues in the future,” she said — words which might allow some RV-dwellers to sleep just a little bit easier.
