No, he is saying it is a poor question to ask. He is stating that there are too many cities to list.

I have not been to England so take my input with a grain of salt, but my wife grew up outside of Manchester, and has described to me numerous times that almost every city/town is walkable, there is little need for a vehicle, and the country is relatively flat. Town centers are comprehensive, and people generally don't have a need to travel far from where they live to fulfill daily necessities.
