You do not have to put up a cookie banner when you are only using technically required ones ornnone at all. Make a dedicated cookies page in your footer and have a table with every cookie, their name, their description and use as well as how long they last.
If you have none, put that info on that page. All you need to do.
Totally with you, but tire dust is one of the major pollution particles from cars, maybe even the worst AFAIK. That, sadly will not go away but it is still leagues more desireable to have everything on electric than fossil fuel. Can’t have perfect stop good enough.
