Why are there save points every 5 seconds?

I believe I read they set up it so you're never more than about 10 minutes away from a save point. I personally think it's a fantastic idea. I can play before going to work without worrying too much about trying to find a place to stop and save. Very handy.

This. It's very conveniant, especially if it's not uncommon for you to get shifts at the last minute every so often. Some games I wouldn't load up without an hour or two left before I had to get ready for work.

Though I would have felt it more balanced to have two kinds, one solely for saving (more common) and then one every so often with the store and everything.
