I lived through Covid without a car, taking public transport for all my transit needs, it was mostly fine, but I was so isolated as I didn't want to risk visiting my parents out of fear that I would infect them, I also never really did anything interesting and mostly sat home.

I now have a car and if shit hits the fan again would actually be able to get out and see stuff, I am talking nature, abandoned places and just being able to see new stuff would be so much better for my metal health.

I am not really doing anything to explicitly prepare, and Sweden managed quite well all things considered.
