If one doesn’t think about it much (and also neglects to consider infection rates in Seoul, Tokyo, and other cities with high transit use) it might sound like a good idea to favor driving solo over transit as a way to reduce the chance of contracting COVID-19.

Except for one huge problem: in San Francisco and much of the rest of the Bay Area, there’s simply no room for more cars. Doubt that? Check out this tweet and video, shot yesterday by advocate and Streetsblog tipster Parker Day:

CDC is suggesting employers subsidize parking for employees so they don't have to take public transit to get to their office. Meanwhile, roads in SF are already at capacity with almost no offices open. pic.twitter.com/KkAgo2qgmo

As Day mentions in his tweet (and Streetsblog USA covered today) the CDC is encouraging people to drive.

Except that, as SFMTA director Jeffrey Tumlin said in an interview in April, “…if San Francisco retreats in a fear-based way to private cars, the city dies with that, including the economy. Why? Because we can’t move more cars. That’s a fundamental geometrical limit. We can’t move more cars in the space we have.”

Does the city need to replace hermetically sealed windows on trains and buses with ones that open to allow cross ventilation? Probably. Does it need to disinfect transit vehicles more frequently? Surely, and that’s happening. Should the city require masks and enforce social-distancing requirements? Yes, and that’s also happening.

Should Caltrans open a lane on the Oakland Bay Bridge to bikes, so people can use the safest, in terms of germ transmission, means for getting between the East Bay and San Francisco? Yes. And if government is going to promote subsidies for a means of transportation, how about electric bikes?

But encouraging more people to drive private cars to San Francisco? Good luck with that.
