I'm a traffic calming consultant in the UK. A rainstorm in the garden is about as welcoming as old-style speed bumps on our streets, to tell the truth. Although they are functional, their appearance is unflattering and they reduce your riding style to that of a pogo stick on cobblestone—quite the paradox, isn't it? Come on in, you cobbler! This speed table has the classic good looks of cobblestones and the modern functionality of preventing automobiles from cutting us off.
