Speed Bumps That Flatten for Slow Speeds

Speed Bumps That Flatten for Slow Speeds by Jae-yun Kim & Jong-Su Lee » Yanko Design: "Today my uncle and I were driving in his truck. We live in the USA, in Minnesota, where it’s currently snowing; his truck has a plow on the front. We were traveling at a modest 10 mph, and suddenly there’s a speed bump, we go over it, CRUNK goes the plow into the ground afterward, we almost flip the truck! We weren’t even going fast, and we were punished!"
