Engineers are brilliant problem solvers. They just need to be told which problems to solve. They are the Can Do team. If we design a city properly, they will make it work. But as it is now, we are living in The Matrix, because traffic engineering goes unchecked and uncriticised. The 85th Percentile, for example, is a joke. An archaic study that doesn’t work. And yet it’s the first thing you learn when studying engineering. Time to change things.
