I’ve always wanted to put a message for drivers on the back of my t-shirt or bike, but have never been able to come up with anything suitably brief. This one, seen in Nathan Phillips Square after Monday’s group commute, gets high marks for visibility and clarity. But I think it’s a bit long for drivers to read at speed, and probably invites much disagreement. So far, my own leading candidates are, “Pretend I’m in a car,” and “No, you get off my road.” The search continues.
