from what i can see, it doesn't look like average suburbia in the US or china, which are basically just copies of the US suburbs (large mcmansions, cul de sacs, sterile landscaping, etc)
it has a very specific english quaintness to it.
fwiw, german suburbs (i was in bavaria) also have a very german quaintness to them.
Here's Benmead Road in Kidlington, one of the places the tourists are reputed to be turning up: https://goo.gl/maps/urEVsQEmRqx
Here's historic Woodstock, which is just three or four miles away: https://goo.gl/maps/M2M9dzXv2e32
Here's Charlbury, another five miles away, where I live: https://goo.gl/maps/EDgNtFERyLD2
And literally 1.5mi from Kidlington, here's Thrupp, with its amazingly quaint canal and pubs: https://goo.gl/maps/Su1Y5uxAGB22
My only guess so far is that there's some slack in a tour schedule, and some jaded tour planner said "take them to a village, any village will do".
stone houses, thatched roofs (or whatever the modern equivalent is), cobblestone streets, roundabouts, little shops and pubs, old churches, gardens and trees, and of course english people milling about... pretty much exactly what pops into your head when you think 'english village'.
looks like kidlington meets the criteria just fine:

this area would be very appealing to someone looking for a slice of english suburbia.

I wonder if people would mind contributing examples of what they see as "average suburbia in the US". Here's a couple of examples to get us started.
