I know that placing utilities (water, power plants etc) further away from the general city is not only a valid tactic - it's generally encouraged, because who wants to live next to a coal power plant? - or get their drinking water from the creek running right next to heavy industry?
Obviously utilities buildings connect to the greater city via power lines/water pipes, so they don't increase traffic - in fact they're quite happy to chug along by themselves, with no transport interaction whatsoever.
But what about civic buildings, like schools, libraries and hospitals? I don't assume it's any more beneficial having them further away (I think they generate a positive aura).
But does having them on the other side of the map increase traffic?
Will the Sims 'simulate' the long commute to get to school or visit grandma in hospital? or do they not care WHERE they're placed (so long as they're placed)?
