Brasil III - A smart challenge

In Brasil, in every village, on every road leading into that village, and, everywhere else for no apparent reason, there are speed humps. Now, in England there is probably a government document that lists the precise dimensions, materials and "rules governing placement thereof" of speed humps. In Brasil it's most likely "got a village?, have a speed hump! No, have ten!"

Now these work - and the villagers love 'em. And the reason why they work is that they are so severe that hitting them at any speed more than "0" results in the vehicle leaving the ground and smashing the undertray. So, speed through the village is a sensible and safe 10 mph.

This is a small training speed hump:

Others I found ranged from a line of bricks cemented into the ground, one that looked like a small telegraph pole bonded to the surface and to a rather ingenious "reverse hump" which consisted of where a speed hump had been and there now was just the trench - the materials now probably in another hump further down the road, or, the constituent part of someones barbecue.

This is just one of the reasons why there are no smarts in Brasil.
