Most people find speed bump irritating. For those with a heavy foot, these bumps can have all sorts of undesirable effects on your car. But, when you have kids and live on a street where people speed, you realize the necessity..

Enter the intelligent speed bump by Mexico’s Decano Industries. With this clever new technology, Decano’s speed bumps will retract themselves automatically for cautious drivers who are going “slow enough”. And these safety devices aren’t even that expensive at $1500 a piece.
