The average walking distance to a pub has gone up a lot in recent years due to closure, and walking on rural roads at night where there is no footpath is horrendously dangerous even if you carry lights. It's a nice idyll but it's no longer really true.
What you say about Simcity is absolutely true though. It doesn't correspond to traditional UK or most European cities at all. Medieval mixed walkable core, maybe not driveable at all; industrialish area down by the wharves now repurposed as offices and residential; Simcity-ish bit on the outskirts where somebody decided to build a grand scheme, like La Défense.
Zoning is starting to leak into urban planning a bit more, when huge housing estates are built with no shops, pubs, or facilities. As far as I can tell demand for housing outstrips everything else.
