Lots getting set as graveyards seems to happen with save games for whatever reason. :| At least I assume that's what it is, as they are not graveyards for me.
One thing I'm wondering, has anyone who has tried it noticed sims walking more often than using a car or taxi? Is this just how the game works, sims are forced to use their own vehicles, and if they dont have one...they walk?
The highway gets a LOT of usage, but I also see sims walking the whole length of it all the time.
I had a similar comment about my world as well. I figured it was because I didn't put in enough sidewalks; just the ones that come with the road, and this caused the walking thing to be more noticeable than in the EA worlds that had sidewalks everywhere. It's just a theory. I haven't played with the EA worlds enough lately to make any comparisons.
