Morning rush hour traffic has become eerily non-existent for the Bay Area after seven counties placed a shelter-in-place order Monday. The new orders by health officers in Alameda, Contra Costa, Marin, Santa Clara, San Francisco, San Mateo and Santa Cruz counties mandate self isolation for millions of residents for three weeks with exceptions to food, essential work and other needs. It seems to be the most aggressive public response to coronavirus anywhere in the U.S.

According to Google Maps, here is live traffic for 8:30 this morning compared to a typical traffic for the same time on Tuesdays.
