There is a new kind of speed bump that barely exists if your vehicle respects the speed limit, but hardens if you don’t. An entrepreneur from Málaga has developed this bump alongside the Badennova company. Inside there is a non-Newtonian liquid that, at slow speeds behaves like a liquid, but at high speeds hardens on impact to create a bump. It is being implemented in Spanish territory and every day there are more requests for it from countries such as the United States or Argentina.
