So Guatemalan riads.... But then I realised, it's not just Guatemala. You just notice it more here. I asked the locals why so many speed bumps? Cause the mitorbikes and cars don't slow down in towns.

That's true but it's not the reason for their placement. The true reason is as soon as a road is built, the people build the town around the road so it's slowing down transport.

Net result: more accidents, more noise, less good sleep, pollution causing health impact , increased vehicle wear, constant jarring of lower back, increased fuel use, and obviously massive impact on trade as all journey times here are double what they should be.

But it really isn't just Guatemala. Why not adjacent to road with entrances to settlements? Are humans just inherently short sighted?
