I know exactly that air of fear that you might feel regarding what you ask above.

I used to fly out and back every week to a project. Now I would not feel safe flying with a vaxxed crew in the cockpit. And while I have always tried to stay very alert while driving, I really keep my eyes open now.

I grew up on mostly old skinny blacktop two lane roads with no line down the middle or sides. When it rained at night, the only way you could stay on your side when passing was by missing the oncoming car by a foot or so. Never worried about running into anyone though. Now who knows?
