Safe Speed Bump
Show me a man who likes speed bumps and I spit on his back too. In the states, the attitude towards speed limiters is no better. And all because it shakes pretty much on such a fence. Even if you drive at a very low speed. One can only hope that someday instead of the asphalt slides, a "policeman", who was invented by Jae-yun Kim & Jong-Su Lee, will be laid on our roads. The meaning of the development is this: when the car travels slower than 30 km / h, the obstacle “misses” under it and the push is almost imperceptible. But if the car goes fast, the “policeman”, thanks to the special design of the hinge, remains firm - and then the lover’s suspension cried with a breeze.
