2. Or bad quality wiring (happens) - you can see the outer insulation cooked/browned/even blackened. Also a burning plastic smell.

I get that the car starts BUT... I'm personally anal about stuff like electricals because when they decide to fail, it's great when it's at home in the AM, but SUCKS when you are nowhere and the car decides to die.
I wish I had a dollar for every person that said "I changed the fuse and all was OK again" without even attempting to find what blew the fuse. Fuses don't just blow randomly for no reason (well not most of the time at any rate).
You missed number 3 - Somebody installed something wrong or that required great power than the fuse was rated at.
