Research shows that wearing your mask, and opening the front passenger window, and the window behind the driver seat helps to reduce the spread of the novel coronavirus in your vehicle. See this NY Times article.
I live in Oakland and work in Menlo Park and I am looking to alleviate travel costs for myself and someone else by sharing commute costs like gas and toll. I would like to eliminate using the bus starting on Wednesdays and possibly working up to 5 days a week rideshare depending if this works for everyone involved. I know we could all use some extra savings and since I received my second vaccine shot two weeks ago I am safe to go. I will still be wearing a mask and taking other precautions like using hand sanitizer etc. I hope to be able to match up with another person or people soon who also share the task of commuting from Oakland to the Peninsula.
