It does depend on the person for sure. I can see 200 being adequate for many cases. It's even still something I'm considering. I'd like to get a small truck again, they are just so useful if you are a homeowner, but I do a 220 mile drive about once a month and that's often enough that I'd ideally want to have that covered. Stopping for a top-up charge on a bathroom break might be OK, but I haven't ever looked at the locations where that would be possible, and if there are times when a wait would be likely, etc.
