CDC: How to Reduce COVID-19 Risk While Riding or Driving an Automobile.

https://www.cdc.gov/coronavirus/2019-ncov/daily-life-coping/using-transportation.html The following statements from the U.S. Government's Centers for Disease Control in Atlanta, Georgia, can be found at the above link. One CDC recommendation that many North Austin motorists may be unaware of: "Improve the ventilation in the vehicle if possible (for example, open the windows or set the air ventilation/air conditioning on non-recirculation mode)". This increased air ventilation in the motor vehicle from a window being open can help to prevent contact from moisture droplets generated by any other persons riding inside the vehicle, the CDC indicated

I myself have not been able to find any information from the CDC on whether a car's open window or partially open window could possibly increase the risk of moisture droplets flying into the vehicle from pedestrians standing on a nearby sidewalk or parking lot.
I have often observed that pedestrians waiting or standing at a bus stop along North Lamar Boulevard a block or so north of West Rundberg Lane in Austin frequently open their mouths in order to comment loudly, or frequently eat or drink at that bus stop a matter of feet from the motorists driving south along North Lamar. Many of those motorists drive by that particular bus stop with one or more car windows wide open.

One possible public-safety issue that comes to mind for me: Is there any increased risk of attempted car-jackings if one or more windows are open when a motor vehicle is stopped at a traffic light here in north Austin? I need to do some online research to find out whether during this pandemic any car-jackings or attempted car-jackings have ever occurred anywhere in Austin at a time when a motor vehicle with at least two passengers in it and a window open was stopped at a traffic light. The above-cited CDC recommendations: "Personal vehicles "Follow the general principles listed above, plus the following. . . "Clean and disinfect surfaces. "Clean and disinfect frequently touched surfaces regularly (for example, the steering wheel, gear shift, door frame/handles, windows, radio/temperature dials, and seatbelt buckles). "When using parking meters and pay stations, consider using alcohol wipes to disinfect surfaces or use hand sanitizer containing at least 60% alcohol after use. Wash hands with soap and water for at least 20 seconds as soon as it is possible. "Practice social distancing. "Consider limiting the number of passengers in the vehicle to only those necessary (for example, choose one or two family members who are not at higher risk for severe illness to run the essential errands). "Improve ventilation. "Improve the ventilation in the vehicle if possible (for example, open the windows or set the air ventilation/air conditioning on non-recirculation mode)"
