Laying a trap for self-driving cars

We spend a lot of time and words on what autonomous cars can do, but sometimes it's a more interesting question to ask what they can't do. That's what this little bit of performance art tells me, anyway. You can see the nature of "Autonomous trap 001" right away. One of the first and most important things a self-driving system will learn or be taught is how to interpret the markings on the road. This is the edge of a lane, this means it's for carpools only, and so on.
