Honest question - I know exactly where the "mask in the car" trope came from and why you're repeating it here but: why does it matter and why is it germane to this topic?
If we were talking about alcohol consumption "slow down and think about it" absolutely makes sense: I might be having fun in my 20s binge drinking but there are very real negative consequences of that behavior long term.
But in the scenario where someone is in their car with their mask on I'm missing the "slow down and think about it" rationale. (Again, I've heard the talking points on this, so I'm looking more for a real answer).
