I've been driving across Europe for decades now, and I have not even once worried about not finding a fuel station on time. Even without nav each most highway stations have a sign stating the distance to the next one, so if you like the excitement of nearly running out you can, but otherwise you just fill up pretty much whenever. The term 'range anxiety' hasn't come into our vocabulary until electric cars for a reason I think: it just wasn't there.

In a very distant past the only worry might've been if I had enough cash currency of the country I was currently in.
