"an hour or two from anywhere else"

A few moments with Google maps and I found two places in Scotland that are ~23 hours apart by car. :-) And Scotland is only a small part of the UK.

Is there anywhere in Scotland more than two hours from any town? Only on some islands, I think (Unst is 2½ hours from Lerwick.)

I don't think so - at least if you exclude islands and villages on the mainland not connected to the rest of the road network (Inverie being the only one I'm aware of).

I was contemplating a post-lockdown trip to Shetland and was looking at the ferry times to Papa Stour which made me think of this!

NB 14.5 hours to get to Lerwick from where I live in Scotland and a couple of hours to get from Lerwick to Papa Stour.

If you allow private roads - then I think Fealar Lodge is about 2 hours from Pitlochry.
