This seems fun!

One speed bump is an annoying but understandable tool for slowing the flow of traffic in a residential area.

Two speed bumps in close proximity are pretty obnoxious, but they do effectively drive home the point that somebody really wants you to slow down.

Three speed bumps... well, there's just no need for three speed bumps. Under any circumstances. You're definitely dealing with some assholes in this situation, and you should probably get away from the area as fast as possible. If only there weren't these three speed bumps slowing you down.

Four speed bumps qualifies, I think, as some kind of a post-modern art project. It's something that has value in its valuelessness, like a canoe made from tissue paper or a toilet bowl seat covered in spikes.

Five speed bumps? Would any monster even dream of realizing such a scenario? Apparently, yes:

This has to be some sort of a message from a race of ancient aliens or something. Something that our feeble minds cannot even begin to comprehend. Otherwise, there's simply no reason for this.
