The two professors noted that due to the air-tight design of today's modern cars, the concentration of particles inside a car from a person with Covid-19 who coughs every few minutes can build up as the particles have no where to go.
They presented a model showing the levels of virus concentration in the air inside a car after 72 minutes. There was a significant difference in concentrations by making one small change: opening the windows.
"...even cracking one window open just 3 inches can keep this at bay. So the next time you're in the car - be it your own vehicle with others or in a taxi, Uber or Lyft - it's all the same advice: Open up the windows just a bit, even if everyone is feeling fine."
They also recommend not keeping the air on recirculation mode.
