I don't recall what prompted this comic. I am curious why sketchy means what it does (undesirable, not the best area). Is it because a sketch is your first pass at creating a piece of art and therefore rather rough and unfinished? I could see that being the meaning. Per Merriam Webster, that is the reason.
My last workplace was on the edge of Baltimore, and I many times wanted an option in Google Maps for 'avoid sketchy areas' because wow, there are places I want to avoid around there. I'm not sure how they could do that in a PC way though - what would the factors be?
