Re: Hills in the morning or at night?
I can't speak to the Prius per se, but I did actually change my morning driving route after I bought my 2010 Insight for just this reason. I did this chiefly to let the CVT warm up a bit more and was less concerned with the ICE.
As I leave town on my old route, on the south side of the river, I used to hit a fairly steep hill immediately and wasn't comfortable stressing the CVT before the fluids had a chance to warm up, so I now cross a bridge and travel on a road north of the river which is much flatter.
I don't think I would actually base my choice of housing location on this single issue, but if I had no choice but to climb a hill first thing in the morning I would probably let the vehicle warm up a bit more than I do now.
